Is there anything here I could use in an audio build?

[Sweetfoot]

I recently picked up some old electronic equipment that appears to have been used in a TV station sometime in the 60s. I figured at the very least I could salvage the chassis, faceplates and hardware, but I was wondering if any of the electronic components could be repurposed for a mic preamp or compressor build.

The piece with the blue faceplate grabbed my attention, and turned out to be a Ceco model 1019 "video amplifier". To my amateur eyes, the circuit looks like it might be similar to a line amp of some sort. There is a gain control on the front panel, and two adjustments labeled "HF" and "LF" on the top of the chassis which make me think there may even be some sort of filtering built in as well.

The other pieces include a Hewlett Packard distortion analyzer and couple absolutely massive high voltage power supplies that I'd be nervous to mess with.

Any suggestions are welcome

This tube unit is good candidate for new tube amp project. Some of the tubes seem to be broken (white=lost vacuum) but I bet the black steel tube are still ok. Case, knobs and meter are great. The transformer could be nice too...

Overall a nice find.

PS: stay away from the old capacitors- do not try to reuse them.

Great haul just for those bakelite knobs alone.

Chassis, iron, tubes, load of usable stuff except electrolytics

Thanks! I plan on tossing the caps, but I'll test the tubes and see if any still test good.

Would any of the absurdly large transformers in the power supplies be useful for anything audio related, or are they not worth consideration? Would there be any reason to fix up the power supplies to power other units in my rack, or would they not offer any advantage over modern power supplies?

I can see that large variable capacitor. Put it into use with this bandpass filter.

Yes! This is exactly the type of project I’m looking for, thank you!
