Anyone know what these were?

Massive windtunnels with 16 TO-3's, look like from the 60's. Anyone know what they were?

Are you sure it's for audio? to me it seems more like a light dimmer or some kind of power supply regulator...

Or a massive PA amp? Has it any connectors?

You mean like the one in "back to the future"...

Part of a motor speed controller, old news.

Doc Brown's prototype flux capacitor. definitely.

If that came out of a De Lorean, no wonder the company director made a career move !

No idea what it ws used for, got it from eBay for use on a massive amp. Right now these might go into a Krell KSA-50 clone.

Any ideas what the Thermal rating on these would be, I'd guess they can dissipate between 0.5kW to 1kW with a good fan.

They are a good 15lbs each or so. The connectors are on top via terminal strip. 2 large resistors mounted on the convection area. The metal cans are RCA types, all 4 quadrants are electrically Isolated. I am guessing one of these is good for a 150watt Class-A or 500 wpc class-AB amplifier.

And ofcourse could use some dipping into an industrial strength cleaner... they were probably stored for over 30 years without use.
