hey there first time poster here.
i have a late '60s ampeg on which i recently replaced the 2 prong outlet to a 3 prong. it worked and everything was fine but then after a couple weeks it started not to put out any sound although i can still hear the reverb tank. i am assuming that this means it is the input or maybe the 12AX7 preamp tube. would i be getting any sound at all if it was the tube? wondering if anyone has ever had a similar problem. thanks in advance for any help.
here is a link to the schematic:
