Single 12BH7.

Looking for info & circuit. Albeit surplus to requirements & dirty. I will still check it as everything seems to be their.

Screws were missing from front & a wire has been cut, so it is patently obvious that someone has been in there fidling.

This is very similar to the SWO-300 only model is not on the dial, it is where Sanwa is on the SWO- 300. One cap in it is stamped 1964. Which is about right and it may in fact, share the same circuit?

I am also getting sick of seeing two wire mains cables with capacitors taking the metal case to Neutral (you hope).

Downright dangerous practice.
