So let me take you back. I have this amplifier from 75' the output transformer I thought was going bad. Lots of fizzing noises, low output, bad distortion. Etc. then one day it basically made a non stop fizz and bad noises and I decided to check plate voltage. I forgot my meter was in current mode and shorted the plate to ground. No sound. I thought to myself. Crap! I killed the transformer but i don't care because I needed a new one anyway. Well. My new one came in and still. No sound. Now when I check plate voltage it is at 940mv. Soooo. Not good. The led lights up but kinda dim at that. But no more dim than before. what shall I check? Sorry for the messy output transformer wires I haven't Cut them yet
