Thanks for the tip. I have a note about a power supply mod that might
need to be made, too. Is deoxit the same as contact cleaner? I bought
a can of that two years ago for the old synthesizer I am trying to get
working again. I am going to go through and clean all the tube
contacts this weekend. I even found an old tube-remover tool, it looks
like a kitchen tongs with rubberized tips. Hope to be able to afford a
tube tester soon, but they seem to be over $50 if they are any good at
all, and the prices are rising on ebay by the week.

What do you look for in a tube tester for this era of equipment?
