It's not too bad as long as they let you have hot water. Eating dry is not fun!

It could be loaded with toxic chemicals! PCB was used quite often in transformers and capacitors. Polychlorinated biphenyls are in a lot of old equipment.
Very , very bad chemicals.

So I need to find the right way to remove the old caps,maybe gloves and a fan? He took a saber saw and cut top of can containing cap right at the end. He wasn't wearing protection but he may be dead now too so I need to be carefull.

Look for ones where the oil is not released.

He put new axial caps in the can then put lid back on.goin to research before changing anything take while to clean everything thoroughly will be a fun project

I think I have a 120v version

 

[Tweetybird]

AM/CW SSB (BFO)
1.5 - 18 MHz...160 meters thru 17 meters
The BC-312 is a rugged and uncomplicated receiver to work on, but sometimes you get problems with the mechanical dynamotor (works like a motor with a mechanically coupled alternator) and many sets have been modified to mains operation with an external mains power supply bypassing the dynamotor.
The BC-312 is intended to be powered from a car battery from 12 - 14 V DC, the high tension(voltage) is generated by a rotary converter, a so-called "Dynamotor".

Mine was an original 120v version
