Title: What's your fantasy amp?
Post by: Corey Y on February 13, 2012, 02:34:24 PM
What's your fantasy amp? By that I mean something that doesn't actually exist that you wish you had. Merge aspects of multiple amps, add or subtract features, different output power, whatever.

I'd love to have the tone of my 1970 Traynor YBA-1, but with some more modern features. A power section with 4 EL34's (has 2 as is) and a power scaling feature to run at full, half or quarter power, with switchable impedance, a DI out and built in fans (right now I have a DIY one made out of a PC fan and a cell phone charger stuck in w/ velcro). That way I could practice and record at home with a smaller cab, without shaking the dishes out of the cupboards, and I'd have some flexibility to use multiple cab configurations when gigging. I honestly don't need twice the wattage, the YBA-1 is pretty damn loud through my Ampeg 810e when gigging, but it's always nice to have a little extra juice if you need it.

59 fender deluxe on one channel, marshall 18 watt on the other. vairable .5-100 watts,  tremolo, reverb, fits in my pocket like a credit card and is free.
Title: Re: What's your fantasy amp?
Post by: dunwichamps on February 13, 2012, 02:57:18 PM
everything up to fits in my pocket and free is doable. However those 18Ws sound the way to they because of the power amp and phase inverter setup.

6550 based ultralinear 200watter with pre/post gain, bass/mid/treble controls. 2/4/8/16 taps for impedance. That's it. Monster clean power. Simple as possible, 100% user servicable.

Sounds pretty close to a Weber AB200, although I'm pretty sure they use KT88's instead of 6550's. Given how many people go crazy for preamps and pedals I'm surprised there aren't more just high powered clean tube amps out there, optimized as a platform for pedalboard junkies.
Title: Re: What's your fantasy amp?
Post by: dunwichamps on February 13, 2012, 03:08:03 PM
the ab200 probably runs closer to 250-300W with 6 Kt88s at 550-600 plate volts so idk y they called it ab200. hehe

You need a good driver setup if you wanna run mondo power in the output section, like a DC coupled grid leaks so you can run the amp into AB2 (ie grid conduction). This is done on the SVTs, and the AB200 and on 1 of my upcoming super clean pedal players amps and on the my 200W GT120 style build

300 tube watts and an 8x10, no logos on anything, sounds like an ultralinear Super Six, takes pedals very well, looks old, reverb, vibrato, functions well with guitar or bass. under $500.

thats a kool idea, like super mondo Fender, would be nice with harmonic vibrato and verb, 6 x Kt88s in UL. Maybe a clean preamp one side with a bass centered bax stack out of an SVT and the other a traditional fender channel cascading into 6v6 driven reverb and harmonic vibarto.

the only kicker on that would be controlling LFO in the verb circuit when u slam the volume


500 bucks lol. thats a true fantasy figure there

single knob?

800-1200 depending upon setup

the champ is SE i assume you would convert to a Fender Tweed phase inverter with 2 -4 El34s/6l6s

How does that work exactly? Do combo amps like Champs have a fixed tone stack or just no tone stack? Apart from power obviously, assuming they weren't dimed, would something like Princeton sound similar to a Champ if you just kept the knobs at noon?

I should just re-title this thread "Hey Nick..."  :P

Yeah, well... price is why I don't have one. Honestly I'd feel crappy looking at an enormously expensive amp in my rig. If I come into some money, though, it's on the list.

champ is probably the simplest amp, 2 cascaded gain stages, a single volume, into a SE 6v6. Nothing is as raw but the closest thing would be a Tweed Deluxe, that has just a single tone control, 2 volumes, for the individual inputs. If you need over 8W then a push pull amp is needed so a phase inverter is needed so something like a Tweed phase inverter works with the addition of just one more gain stages in front of it that would be like a Champ/Tweed mix up

sorry your playing to my vanity....

It's a slow, rainy Monday and everyone else in the office is out sick. So I'm in daydream overdrive. I also had half a pot of coffee to myself.

The one knob amp thing plays to my deeply seeded utilitarian tendencies. Along with my suggestion that bands just be issued numbers or bar codes instead of coming up with dumb names or my rant to my wife about what a waste of real estate and resources front lawns.

So yeah...a big black box with one knob on the front would do the trick for me. As long as it sounded good, obviously. I could do a lot of tone shaping between playing style, instrument and pedals. I pretty much leave my YBA-1 with all knobs at noon except the volume.

Post by: dunwichamps on February 13, 2012, 04:06:11 PM
something thats 6 x Kt88 in nature is going to be push 2-2.3k given the nature of the transformer cost. you could shrink that cost down with say a 4 x Kt88 setup would be 1.8k-2k
Title: Re: What's your fantasy amp?
Post by: SoupKitchen on February 13, 2012, 04:29:59 PM
A head with good-sounding spring reverb that isn't taller than it is deep.  Maybe something with a 6G6 Bassman front-end, but the cathode follower would feed a Bax stack.  AC-coupled long-tailed pair and four EL34s running ultralinear with cathode bias, say 65 watts...and Fender three-tube harmonic vibrato...and pentode-driven reverb a la Fender 6G15...in a sidechain (parallel to the preamp).

Nick, when you say "tweed phase inverter", I assume you're talking cathodyne? Since the majority of tweed Fender amps had those and the LTP came in at the very end...
Title: Re: What's your fantasy amp?
Post by: dunwichamps on February 13, 2012, 04:39:01 PM
yea the Tweeds had ac coupled cathodyne phase inverters, where the LTPs came in on those bassmans later on I believe.

"Fender three-tube harmonic vibrato...and pentode-driven reverb a la Fender 6G15"

that what I had in mind for Disco's request, the harmonic vibrato can also be done with 2 tubes as well.

also driving a bax with a CF does not help the circuit much, the losses arent improved which kinda sucks

Post by: bitter on February 13, 2012, 04:57:17 PM
I've always wanted another head for dedicated cleans and stompboxes, but I cant justify it these days as I'm not actively jamming.

The old Hiwatts still call me more than anything else. Great cleans and can still get some growl when needed.

It doesn't want to imbed, but this is probably my favorite gear demo of all time. Although, I would generally prefer the 103 model for added headroom.

I had a DR504 for a few years, it was a great amp. It took pedals fantastically, although the tone was so good I just used the amp by itself most of the time. It sounded very similar to my JCM800, which was why I got rid of it. Although I got rid of the 800 as well, not long after. I still have my VTM though, which gets in the ballpark of the tone I liked from both, with a lot more effort for a lot less money. It is balls for pedals though, does not like them one bit.

I am very on board with the idea of a pedal platform amp. Just no frills, clean power, passive tone shaping. My Sound City B120 was that amp for me on guitar for a long while, but it's pretty bright sounding and the active EQ makes it really touchy dialing things in. It was good if I had one dirt pedal (or a combination of a couple) for a locked in, always on sound, after spending the time to perfect the settings. It's my bass backup ATM, even though it's still a bit too bright for that as well. I can't bring myself to get rid of it though.

easy to make it not so bright really. Probably change a coupling cap

Is it something I could do without potentially killing myself? That's a question I need to ask whenever anything related to amp modifications comes up.

To be fair it's a goal I keep in mind with pretty much anything, really.
Title: Re: What's your fantasy amp?
Post by: dunwichamps on February 13, 2012, 05:41:27 PM
You gotta make sure the amp is all drained of voltage, which you can do but need to be careful about. Then you would solder and remove 1nF coupling cap on the brilliant channel and replace it with a 400-630V rated coupling cap of higher value, the normal channel uses a 22nF so if you wanna remain under that value but more bass use 6.8nF to 10nF or you could go balls out and use something up to 68nF if you want but that could get woofy/blocking

Post by: Mr. Foxen on February 13, 2012, 05:50:01 PM
Should probably bear in mind that all controls nooned is pretty rarely flat on a valve amp. Clean boost into reverb return will do it though.

Swapping out components in an SC120 is easy, solder sucker and reasonable iron an its pretty much a joy. Turrets are lovely.

low impedance DC bias point for the LPTI to operate.

Wow never knew about the controversy on this little tube.

there are like half a dozen different DR models with different setups on the phase inverter, how it is biased, how the follower works to bias the stage, ect ect. All of them are quite elaborate compared to the usual AC coupled Marshall/Fender LTPI and even more elaborate than my own DC coupled long tail pairs

200W, 6550 power section, gain, master, bass middle treble for the eq. Maybe a mid shift switch or a filter control of sorts. Ability to slave to a power amp. Not a back breaker or a bank breaker.

Voiced a little more for bass but yeah.

Seems hard now days to find a bass amp with no horseshit. No graphic eq limiters no weird crunch feature that sounds like turds. Only thing close is an Orange AD200B but $2,400 makes it cost prohibitive.

orange or120 style pre amp with an FAC that is switchabe to be before the gain stage, or after. a singe tone knob in the EQ section that can be defeated, and a pre and master volume. i think it would be simple and effective.

Well from you and seeing the quality in what you build that price doesn't bother me all that much. There's a blood sweat and tears factor in what you're building as opposed to what Orange is outsourcing and charging even more for now. I'd be more inclined to fork $2,000 to you before I'd drop that cash on an Orange.

wow, if it could be switchable between the 3 that would be cool! and i don't know if it would be a single bax eq, i'm not sure how that would work? i was thinking more of a tone knob like on the older low wattage amps.

can it be done?
Title: Re: What's your fantasy amp?
Post by: dunwichamps on February 14, 2012, 03:50:37 PM
Well it all depends on where you stick the EQ
Matamp style or Orange style

the GT120s run the bax after the 2nd stage while OR120s are after first stage. Putting the FAC b4 the EQ is redundant because the EQ can control bass if u want. So in an Orange they put the FAC on post stage 2 and in Matamp its post 1st stage because the bax is after stage 2

IMO, I would do pre and post stage 1, with a Matamp style location of the EQ.

One knob Bax is easy, you do a dual 1M log pot. then when you turn it right of 12 oclock, bass and treble go up and left of right is bass and treble down. Then add in a phase switch so you can get the other option, turn up and bass goes up and treble goes down and turn down and bass goes down and treble goes up. All on one knob, with a single switch

You could run Gain, Pre and Post Phase Master Volumes

well

Gain, FAC, EQ, Master, which could be pre and post master but then its 5 if u do both pre and post

the EQ knob looks just like an single knob EQ the magic is on the inside where u get two synchronized but independent 1M pots  

this is a picture of it

Basically a Laney GH50L with reverb, a bit more gain(just in case), and true crankable clean all times 2 for 2 channels. That would be the perfect amp for me at this point. I'm not even sure I would ever use the extra gain or use it purely clean. So for now the stock GH I have is fine. The gain on this sucker is perfect for the type of metal I play and it's a really awesome sounding gain, it's not muddy yet it's not overly crisp either. Turn off the high gain and it's a rock machine and very non-master volume to JCM800 Marshall sounding.

Laney makes a couple amps that seem to be close to what I'm talking about here but I've never played them.

not quite, its called a svt "classic", but is a bit different, a few less preamp tubes
Title: Re: What's your fantasy amp?
Post by: fallen on February 16, 2012, 08:38:29 PM
I didn't love the preamp section but I really liked the power amp on that Fender Prosonic head that you could switch between a bunch of modes. Tube rectified class A, tube rectified class A/B and solid state class A/B... or labeled something similar.

It was a cool idea to be able to leave the front end set and then get a bunch of variations of tone from the power section. Would be great with a Matamp front end.

"fantasy amp" means something that doesn't actually exist, right?

cos I really really really like the Bogner Uberschall

but i have no use for a clean channel - i prefer to just use the volume knob - and 100 watts is silly

I'd buy the shit out of a 50 watt single channel uberschall amp, for sure

Matamp/Orange design for bass so a GT200 or AD200B, with one as a slave unit -pure volume- and a master head for the controls. The less controls the better, I want pure and sweet tone so master, volume, treble, bass & mids. Everything else I don't need. It has also has to take pedals like a motherfucker. The lower the price the better. Coupled with a couple of 2*15 and a couple of 4*12 to get the maximum out of the rig.

I sent it to these guys last year for an overhaul:

It came back sounding like very loud angry sex.

Asked them to brighten it up a bit, it had Svetlana tubes (I think) when I got it and was pretty muddy.  Probably old tubes, but the difference before and after is like night and day!  Mesa tubes in it now.

Would there be much point in having one before and one after a overdrive/distortion stage? My way of picturing a preamp works off time spend putting pedals into a clean amp, and eq before and after drive does pretty different stuff.
Title: Re: What's your fantasy amp?
Post by: dunwichamps on February 27, 2012, 09:04:30 PM
Before the clipping changes the way the clipping occurs while after simply accentuates the clipping parts.

If you just using it as a clean amp then it doesnt matter really, if you expect little to no amp distortion.

that amp has a nice inverter setup which is similar to an SVT, They use a low gain cathodyne to split the signal then 12au7 drivers to add some gain but also improve output impedance to the load of the grid leaks which are small for 4 x KT88

I had a dream about amps last night.  I also had a dream with Dwight from the Office but he wasn't playing through this amp so I guess that doesn't matter.  In my dream there was a 5E3 Tweed Deluxe  inside a larger amp.  Not just the preamp but the entire pre and power amp and transformers and instead of the power tubes feeding speakers it feed into a quad of KT88's so that I could crank the tweed and then turn the KT88 side to whatever I want and still get all of that sweet power tube distortion and rectifier sag.  It's like an integral reamp.  Is this at all possible?

I had a dream about amps last night.  I also had a dream with Dwight from the Office but he wasn't playing through this amp so I guess that doesn't matter.  In my dream there was a 5E3 Tweed Deluxe  inside a larger amp.  Not just the preamp but the entire pre and power amp and transformers and instead of the power tubes feeding speakers it feed into a quad of KT88's so that I could crank the tweed and then turn the KT88 side to whatever I want and still get all of that sweet power tube distortion and rectifier sag.  It's like an integral reamp.  Is this at all possible?

you would need to dump the 5e3 power amp into a resistive dummy load, say a 50W 8 ohm resistor. Then you would take the output and bring it to a slave amp which has a quad of 88s and a phase inverter.

The simpler thing is just to build a 5e3, a dummy load wit line out and a Kt88 power amp

I was thinking that you could have setup where you could have multiple amps into this outside power amp so that you could have a tweed deluxe and a jmp coming out of the same speaker cabs at the same volume with their own unique voice.
