no way to be sure. i'd guess resistors or diodes. what connects to them?

they produce a lot of heat.

Looks like selenium rectifiers.

>>926727
This guys right they are selenium rectifiers

>>926727
Correct, they're selenium rectifiers, which means what you've got there is pretty goddamned old.

As if the wax paper caps don't give it away
Having said that

OP those caps have to a-go-go
By now they leak worse than a grannies bladder. Swap them out form the appropriate modern equivalent.

Selenium rectifiers - dangerous. When they fail they emit a nasty gas. They have a voltage drop that you have to simulate with a resistor in series with the new silicon diode.

also if you undo the bolt holding the stack of plates together, the rectifier will be destroyed.

no it won't you retard.
