The supply looks like an officially commissioned U.S. made product (or a lovingly rendered copy).
If I read your opening post correctly, you do not have a C60 mic to go with this supply?
You can still use the supply with any AC701-powered mic, other than a C60, as long as you:
* remove the audio transformer from the DIN-to-XLR audio output chain
* get the supply into a healthy state (checking caps and resistors)
* assign the DIN connectors correctly, to correspond to your mic, and
* carefully ramp up voltages on first turn-on, not to stress the AC701.
In the end, you want to measure 4.00 VDC max for tube heater and 120VDC for B+, the former measured at the mic, not the supply.
