I've lost a right channel. Again... This time all the cleaning and deoxit in the world could't help. I could see my 1KHz signal from the switch board entering the volume pot, but on the tone control PCB, only the left channel was live. Darn it! So I've watched @Kale do it, and I got a little jealous, and I also figured, what the heck, if I don't get this right I'm gonna need a replacement volume pot anyway, right? So I started taking it apart like this:
and pretty soon, wafer after wafer it was reduced to this:
and finally to this:
I used about half a can of D5 and a toothbrush, plus some autosol metal polish to get it all clean and shiny:
and then it was time to put it back together (I used JBWeld to lock the shaft back in place on the last wafer):
I don't know why that back panel reads 250KΩ for the VR's on this thing, all of them are well above 360KΩ, but whatever... so, I closed it up:
and voila - disco!
