I had put in a bad tube before the recap and blew apart the 1k 5W cement resistor.
I replaced that Cement resistor and all the caps, even the coupling caps. I double checked and apparently did things correctly. There are no screen grid resistors on the tubes as stock- its a little Traynor Bassmate.
Is it possible when the bad tube blew up the cmenet reistor, it took out other resistors?
I am going to need to take it to a tech, unfortunately the only reputable tech in my area moved to Maryland ( The Ampmonster).

Where are you? Maybe there is someone else that someone will recommend.
Re: Recap done. Tubes Redplating
I assume this is the fixed bias version of the Bassmate. The 1K 5W is the dropping resistor for the screen supply, so you likely had a screen short. If it shorted G2 to G1, it might have taken out the bias supply. Both tubes redplating? You say you replaced all the caps; including the bias cap (C12)? Could also have damaged the grid return/bias feed resistors (R22, R23) or the 1K5 grid stops (R21, R24). Any tech will be able to tell if you lost negative voltage to the grids.

Great advice, people great advice. Deeply indebted. Thnx!
