it was laying in a pile of junk behind a shopping center. It looked like it had sat thru a couple of rainstorms. One of the pots was completely encrusted in rust (replaced it). But the tubes were intact and no cracks in the circuit boards. I set it out in the hot sun for several days to dry it out and after much scrubbing and scraping I got much of the remaining rust off. I then did resistance checks since I had one to go by. I went thru a whole can of contact cleaner cleaning the switches and controls. When everything checked, I powered it up. To my surprise, no smoke and it worked- well, sort of. I had tremendous vertical non-linearity, so I went thru the vertical circuit. It took a while working on it, off and on. But I always remembered one thing an old chief engineer told me. If it worked before, it can work again.
