The relay makes me think jukebox - the heaters were switched on as the play cycle started... 4 2A3s and a 5Z3? No sockets for small-signal tubes, which would be 5-6 pins.
Tom,
I concur in your analysis. That thing is OLD. I see no evidence of 'lytics, whatsoever. Is that a rubber band I see holding a 0.1 μF. axial lead cap. in place? That might be the only cap. that needs "automatic" replacement, as the PSU parts seem to be "oilers". I wonder what is concealed by the tape wrapping. Do you think that there a 2 channels, for a pair of speakers? Where are the power and I/P signal connections?

I don't think it is an amp at all, but possibly some sort of power supply for who knows what. I'm more or less clueless, but I think I see a lot of recognizable rectifier socket wiring (at least 3) and not much else..
Neither do I. I enlarged the picture and took a good look. There are three cut cable bundles that were probably for power feed and control to and from something else.
