'82 JCM 800 4104 Service and Mods
#4
Small update: after pulling the chassis and turning it on again, it's making sound. Not sure if something fixed itself in the process of being moved around or not. I was able to reproduce the distorted output though, only on the high sensitivity input. Interesting... Hopefully I'll have more time later this weekend to poke around. Also, seems like mine is from early '82, it's plate voltage sits about 400V even after warming up. My understanding is that later on they went to around 450V.
