    yes, there is a relay in the case. Creating a schematic is a good idea. I'm thinking that was added.

    Yep, the riveted parts to the chassis and the 3 rather unique mounts is the give away. The two tubes may be for two separate voltage windings as one WAG.
    With a 260W continuous rating there is lots of potential for intermittent ham use.

    OK one tube definately 5V filament rectifier, the other may be a gas VR tube. Those type numbers started with zero because they had no filament voltage. So maybe a 5-600 V B++ line and a lower voltage B+ rail with regulation.
    I would not power it up because the electrolytic fiter caps are probably all dried up.
