Re: champ extra gain stage
That's to bad yours isn't working that well. I played mine for an hour today when every one was napping.
I set the master at 3/4 throttle and lo gain 3/4 throttle and high gain at 1/2 for some nice crunch.
For more gain I dime the lo gain and high gain about 3/4 for Marshall style gain. Setting both lo/high full throttle isn't better sounding I prefer it backed off.
To clean things a bit, Master to full and lo/high at 1/2 throttle. I tried my strat today and SRV tone was happening using neck pickup.
Never thought I would enjoy this dumb little amp but I do
I'll have to get Benoit to come over and test drive this amp so he can give an honest report.

Re: champ extra gain stage
I don't use master volumes.
I feel if the amp has to be turned down then either it's too loud for the place your using it or there is too much gain.
I played many years with Fender and Marshall amps from the 60's and early 70's without master volumes. I put the volume on 10, treble on 10 and the bass & mid on 0-3 the most. I usually use the neck pickup.
I started playing guitar after I saw the Beatles on the Ed Sullivan show and have been playing blues based music in bands since I was 15.
So I have my own ideas of tone/sound and playing. Here's myspace page:

Re: champ extra gain stage
Well to get back to your original post there are so many threads on this very same subject of Super Champ type thing but here are some schematics.

I also saw the Beatles on Ed Sullivan and never look back on my guitar playing.

Thanks for the schematics.
The Class Act schematic is wrong/modified as far as I know. I know David and he sent me the original, he's a good guy.

Re: champ extra gain stage
Makes me wonder why you are asking us for help when you know David Are you fishing for something there guy?

Haha... You made the same mistake I did mark, the guy who posted right above you is Big Daddy, and is NOT the original poster, bigsmittyM Fowler wrote:Makes me wonder why you are asking us for help when you know David Are you fishing for something there guy?

Re: champ extra gain stage
Yes I am the original poster I think Im going to try an express preamp and see how that works.
Re: champ extra gain stage
Well shucks I am wrong
bigsmitty that TW preamp into SE has been built before and should make for a good amp, lets us know.

Re: champ extra gain stage
Another discontinued Allen amp for your consideration:
The 5f1+
Would more accurately be described as a 5f2a+.
Anyhew...hot rodded tweed princeton, with the whole bag of tricks thrown at it.
Choke, filtering, 6L6/EL-34, extra gain stage, ect.
If one were so inclined, it would be very easy to set the extra tube (v1) up in parallel for some additional punch and gain.
Why let that extra 1/2 12ax7 just sit there all lonely and unloved...have a heart...
- Install 1-6, 2-7, 3-8 jumpers,
- Swap the plate resistor from 100k to a 50k,
- Swap the V1 cathode resistor from 1.5k to a 820.

Re: champ extra gain stage
bigsmitty I thought I recognized that name hello Mark.
Re: champ extra gain stage
Just FYI a really good way to increase gain on fenders is raise the value of those wimpy little 15K mid resistors. It also makes the amp fatter and sound "bigger" than it actually is
It's true i've lost my marbles and i cant remember where i put them
Re: champ extra gain stage
Mine is wired like 5f1 no tonestack so no mid resistor.
