Ok, finally got them finished. I managed to get the "correct" pilot lamps @360v rating - same a the ones used on the JTM45 & the original 18W.
I also fitted larger & better mosfets. I have got trems to work - I replaced the ceramic disc capacitors in the oscillator with 3 red/brown Xicons -you can see them in the pic below lined up on the edge of the board. I am not sure why, but that's all that was needed.
I made some foot switches for the trems.
I have also managed to clean up all hum thanks to a tip from Atilla. He showed me how to hook up a capacitor to make a probe. You plug it into a PC speaker & can detect/islote hum. I used this to move a few wires around & in 20 min I had cleaned up both amps. Great tip - Thanks Atilla.
I been trying out a few valve combos. I was luck to find some NOS Amperex (Holland) 12Ax7's & some Phillips Miniwatt (Holland) EL84's & think they really sound great. I am really impressed with the Russian NOS valves though. To my ear they sound really good. They are long life tubes & really cheap compared to other NOS. I have also found 6V6GT & 6L6 equivalents & am keen to try them out.
EZ, Singemonkey, Chris - I want you to listen & give your opinion.
Now for my next project...
