Default Large Amplifier Torroid and Softstart Board

Hello all, I have three torriods to sell with softstart/control bipolar psu boards. They are from Crest/Apogee amplifiers that were scrapped. The transformers and control boards are all functional, in good condition, and the softstart works great.

Specs on the transformer are-
primary 100/120/230v selectable
secondary 100-50-0-50-100 Approximately 10A for the 50v winding and 5A for the 100v winding so about 2KVA.
there is also a smaller 23-0-23 secondary good for about 2A.
I think the transformer has an internal temp switch for triggering protection.

The control board handles voltage select and mains control for power up, softstart for the transformer, bipolar psu for front end power, and aslo has some protection circuitry that would interface with external sensors/control signals. There is a front panel pcb with three leds for status and also a control switch for power.

Asking $40 per set.
