Hi again hope your all doing fine.
I hope this to be a short post and a quick repair (not on your nelly) but i found it interesting so thought id ask you for your thoughts!
I got the beast today, opened it up and found a Sovtek 6L6W in location V4 along side 3 JJ EL34s!!. So just to put that right, El34 X3 & 6l6w x1.
I fliped the amp over and resistor's r6 and r9 are blown on the main board. No other damage just them two resistors, r9 is blown into two parts and lots of carbon on the board, r6 not as bad but is blown.
Q1. Would the incorect valve have caused the resistors to pop? it was the first thing to enter my head. Im not too clued up on valves so im hoping one of you guys can say ""hey yeah thats a stupid thing to put that valve in there and thats your problem pal"".
Q2.Will i need to bias the amp after fitting the resitors and another valve and what values please.
Q3. What do you recomend i do about valves? I have an el34 knocking around that i can pop in for testing along with the three that came with the amp, will that be ok or shoud i buy new ones first.
I'v had a good read around about the boards being s**t on these amps and it looks like i do have the early board. But i wanted to ask your opinions on this one first.
Thanks
I think i have the new style board, dark green and has stoc number in right place
