Wow thanks everyone for all your helps!
Simple se in triode only sounds so good, and plays loud enough even with el34's so I don't think I'll even do the U/L & Cathode feedback.
I would like to measure all the things i should measure.
Do I need to measure the B+ where do I put the test leads?
I fired it up and let it cook then turned it off. measured the resistance of the cathode resistor(s) (I have a switch to select 680/600/560/540/520.
The resistance value decreased rapidly after the amp was turned off. Meter was still on voltage, and was still measuring some small dc voltage 10 seconds after turn off.
Should I just assume the resistance of the cathode resistor?
Thanks for all your help,
pics to follow (at some point)
