Identify Flea Market Amp

[J M Fahey]

J M Check out the image of the underside of the amp. It has a hole with a grommet that has 2 wires coming out about where the unidentified thing is on top of the chassis.

Ok, half the riddle is answered, now confirm/check where do the back panel terminals hook to.
No, "look at the picture" is not an acceptable answer, itīs your problem, not mine.

The resistors are 100K 1% or 130 ohm 1%. Probably the former. Check with meter

I grew up in a time well after anything was built like this, but...

Any chance those terminals could have been used to power a peripheral piece of equipment? I mean, I have seen octal tube sockets used for such a purpose. And chances are, this thing would have been semi-permanently installed in an office somewhere.

I'm just thinking and asking out loud; any validity to my question? ... also, anytime I get "mystery terminals" in a chassis I'm salvaging, I get rid of them and make a sheet aluminum cover for the gaping hole... time-consuming, but at least my fingers (or my dog's nose) won't go where they might get zapped.
