I believe you're in the right ballpark but the link you provided didn't help me narrow it down. I'm not sure it's an amp due to the lack of controls. It could be a vintage rack-mount power supply for broadcasting or HAM gear. If you can find something more in line with this particular item... something from the period, preferably. Thanks for contributing!


Here is a reference that may help. Judging by the ripped off sticker I'd say its a band sticker but likely not the sticker for the product? It could be a Military Radio AMP power supply. Even if you reject this opinion I think the reference to the site might at least get you in the field surrounding the origin of this device.

You are definitely in the right area but I could not match up the plug connections with anything.
