Hello , I recently got an amp board from a Tangent Amp -50 , just the final board ( u can see in first pic ) and would like to know what power supply I need for it , i know it should be 27 v on primary and 11 v on secondary but don't know the amperage or VA and also if anyone knows, will the amp work without the secondary PS, only with 2x27 V , from what I understood the secondary supply (2x11V) is for the muting circuit.
The link below is the service manual for the amp if it helps.

Hi gable this amplifier runs on +_ 37 volts dc. The other voltages power the ls protect circuit and also the pre amp .I have the same board amplifier board running on just the +_37 volt dc . I don't need to power pre amp nor do I use the ls protect circuit . This amplifier sounds surprisingly good . By the way the schematic is wrong I have a corrected version somewhere I will dig it out if it is of any use to you
