Question what are these....maybe amplifiers???

I was given about 30 of these along with a truck load of random rca parts

Does any one know what they are?

All i know so far is that they appear to be made by rca.

Perhaps small amplifiers?

There are slip on wire posts labeled

These are the numbers I found on them
code B

They have a trim pot
two rca transistors (2n6387)mounted on a heat sink
two transformers (chokes?)
6 resistors
2 disk capacitors
2 orange drop caps
and a few other random parts

I have had these sitting around for a wile now and would like to do something with them!
If they are amplifiers I was thinking about building some head phone amps?
thanks for the help!

They don't really look like amps.. ?

Maybe they're lighting control modules (dimmers/ballasts?) or some kind of motor control or something..

Or some regulated power supply,
maybe a switching supply.

Transistors are NPN TO220 darlington with a hfe=2500
Could possible be of use in output stage of some amplifier circuit.
Would be a N-Channel amp.

I think you should hook up and measure what comes out of connector pins.
