Love vintage kit great to see it still in service. What concerns me though is the use of PCBs in capacitors and transformers in some vintage devices.

Capacitors, sure, but just because a transformer looks ... absolutely disgusting ... doesn't mean it's prone to failure.

He's saying PCBs used in the sealed transformers I think.

It's not really in service, I found it the other day in the attic at my parent's place. I do want to clean it up and carefully test it. Have to find a variac and a lightbulb first to prevent components from releasing the magic blue smokeir PCB's when powering up.
