Also, the schematic you posted has sense connections which you do not show on your earlier wiring diagram; do your Salas reg boards have sense connections?

Anyway, if you are blowing the rectifier diodes then you are puling too much current through them. This would imply that the regulator is shorted to ground. I don't know anything about the circuit you are connecting to, but you should double-check your connections. You should also fuse your transformer primary so you blow a cheap fuse instead of rectifiers or other components.
Hi nezbleu,

Thanks for your response.
Here you have the schematic how the 5 volt Salas reg is build.
It is weird that de Salas reg perfect works with a second transformer.

I have connect now all 3 Salas regs the plus output of the Salas reg to the receiver board, and not connect the zero to the receiver board.
If I measured between the zero of the Salas reg output and GND DAC I get these values:

Salas reg B -2.15 Volts
Salas reg A 5.30 volt
Salas reg C 5.30 volts

Reg B I get a minus sign on the meter, which is not good.
I take 1 measuring pen in the same place.

I only connect the receiver board, not the DAC towers and 12 volt DC

Regards,
Rudy

Sorry this was offtopic:

Now I ask this question on the right thread: The simplistic Salas low voltage shunt regulator

Total newbie here so see if I can get some love determining if Ive toasted a shiga donor. I dissected the unit and layed it out on a board and removed all neccessary components. IE: tape deck and tuner. I had everything working with speaker and decided in my infinite wisdom that I would try a 7.5 volt dc power pack. Unit is run at 8 volts so I figured I was safe. I triple checked + and - and tested the power supply. It showed almost ten volts but again in my infinite wisdom figured it was showing high because it was not under load. I hooked this up and the unit spun up and showed zeros. I thought ok this is working. Then I closed the door switch and nothing happened. I checked continuity opening and closing the door switch and its ok. I traced the pcb back but it does not appear to lead to the chip but to the corner of the chip and then dissappears. I dont see anything on the other side close to where it dissappears. Anyone got any ideas of where my next step is? Im a big boy and if I toasted it Im ok with that but the diyer in me wants to find out where I might have derailed the train. I cant throw anything out if theres a remote chance I can fix it. Did I mention you guys are great. ( :
