So about that Heathkit chassis from 1957 that I picked up for a future project: Pretty cool, huh? I got it for the chassis and the PT, and scrapped the rest. It stunk like ash tray and old oily rags. Concerned about PCBs, I lifted up the transformer to see if it was leaking oil: As you can see it looked like it had epoxy or bakelite sealing it up. That chunk was already missing out of the center, and since I saw no oil or oil residue, I figured no oil means no PCBs. Right? I also took a screw off the nameplate on the top, stuck a wire deep down into the hole till it bottomed out, and it came out clean. No oil! Well, the future project is now. Recently I took the whole thing apart to clean up the chassis. The ashtray smell went away and the oily smell got worse. However, looking at the transformer when it's completely free, that's not epoxy nor bakelite. Instead of being hard and brittle, it's thick and squishy. So it's either dried up oil or (more likely) wax: The Internet says that sometimes transformers were potted in wax (not unlike pickups). Sometimes, the wax contained PCBs, just like the oil did. So what's the likelihood that a transformer like this would contain PCB-laced wax? I can buy a test kit and find out, but they look spendy. It would be cheaper (and more definitive) just to dispose of this at a local hazardous waste collection site and start over. I'm new to all of this but I know a lot of you guys have been round the "Ancient Ebay Parts Chassis" block before. Does anyone know any fast and loose shotgun tests to determine PCB content? I can't tell if I'm being over-paranoid or under-paranoid. It's all going to sit out on the porch until I figure out what to do about it though.
