Got power supply up and running. All the outputs test good.
However, when I placed the rectifiers into curcuit the amplifier will not start just draw strange current and flash protection very fast. I believe the last Amp. Like this I worked on the cause was one of the 78M05 on the board causing it.
Is this the output board?
Should I remove the output transistors for testing?

No shorted output when I received it. However, I can see that someone has changed the regulators previously
Well 2 of the three have been changed.
I have 2 extra cards with new ic on them.
Something burnt the power supply up badly?
My power supply just clicks fastly, these amps have done this to me before. Generally beacuse an output is shorted.
A different output card makes no difference.
