It is actually my amp But my friend Jstrat posted it for me since i do not have the ability to do so.
The tube layout is 2 12AX7's, one 12AY7 and the power tube is a 6NS7GTB.
The amp does not seem to be a priduction amp but a one off. Anyone regonize the circuit?
The front left to right is input, bright toggle, V, T, M, B then a pilot and a "standby" and "power" toggle. There is no name on the amp anywhere just a silver dollar sized logo on the front that shows a wolf howling with the moon behind it.
Any help is appreciated , thanks in advance

It looks to be a Trainwreck 'knockoff'?
Ken did do a number of unofficial amps. This amp's circuit doesn't match the description of any that I know of. But whomever built it was careful to duplicate a number of Trainwreck signatures with the build. The Budd chassis, the coltrol layout, etc... Even the knobs. Most cloners don't seem to trouble with certain things. That and the fact that the circuit is NOT a known model means that no one was cloning anything. This makes me wonder if it may be a Ken Fischer build. It would help to see some good pics and some gut shots.

After closer inpection I'm backing out of the possibility that this may be a Fischer build. I don't think Ken would include two DMM plug test points for user access on any amp. And I noticed that the power filter seems to be a multi can cap and I don't think Ken would ever use one of those. He also diapproved of tube shields. So I guess more detailed pics aren't needed. What you have is a single ended amp project, maybe based on one of the designs at AX84 that includes a faux PI for more authentic overdrive, packed into a reasonable copy of a Trainwreck cabinet. I wouldn't guess it to have much collectors value, in fact it might have more street value if the builder DIDN'T clone a Trainwreck cab to put it in. As such it has a sort of "ooOOH... A Trainwreck, oh wait, it's a fancy Champ knockoff" kind of effect. But if it sounds good there is certainly value in that.

t's a guitar amp at best. Might get enough for a Dorm but not much else.

Why would you think it's a Lone Wolf amp??? Or are you just taking an opportunity to attach a link for some other reason???"Take two placebos, works twice as well." Enzo

no other reason, thought you might want to compare logo's. I can't see the logo very well on the posted pic and I don't know anything about Lone Wolf amps, but lots of amp companies started out making home-made looking products. Thought that might be it if the logo's matched. You could always send the pic to them if you wanted to find out. Anyway, Verellen makes amps that look like that one too. You can google Verellen yourself.Originally posted by rosssurf View Post

If the power tube is a 6SN7 then the amp could well have a PI tube, as it could be a low wattage push pull amp.Comment

Hi JStrat and rosssurf
Yes what we really need to see are some high-res gutshots (3 or more) of the whole amp insides showing socket wiring detail and pot wiring detail and main board detail - infact the whole thing (in focus). Get as many pics as you can and post them back here please. Then we should hopefully able to verify it, (or at least reproduce a schematic which we can discuss - at length).
TIA
Cheers

Hi- I'm new here and just catching up on the forum. This looks like- almost certain by the tube compliment- a low power version of the Trainwreck amp. I have built this same circuit and its available over at the AX84 forum. The 6SN7 is run as a pair of 4 watt output tubes. It even has fixed bias and that explains the Bias taps out the back. I have the same circuit on my web page in an amp I built from the schematic at frugalamps.comComment
