Alesis Prolinear DSP switchmode PSU

[oc disorder]

Alesis Prolinear DSP powered monitor switchmode PSU.
Hard to believe these are cheaper than a traditional PSU when they supply +/- 38v @1 amp and 8v @0.3A .
Think my partner is going to up my life insurance if I start working on these !
Yin Nan makes the transformers/chokes.FuhYin make the capacitors.
I better stop there before I put my foot in mouth !
Any schematics around?

Does it work without the load of the amplifier circuits?

Check all the secondary rectifiers for shorted.

Does it blow fuses or just not work?
