It is a Scott 510 PS/Amp - rercapped and rewired to use the unneeded choke and rectifier socket. The choke makes the PS quiet enough for 3 stages of amplification and the unused socket became the preamp/mixer 6SL7.

Also, keep in mind that none of the modifications are permanent. If one day somebody needs a real 510 amp, a few wiring changes will return it to original.

I'm using it to work on a Meissner 9-1091C right now (the Meissner has no amp on the RF chassis).
