Good point... the only "everything else" I was referring to was the 48V Phantom rail and everything on the automation supply. Not much of an everything....

Tom, I am getting 6.8v across the board and I understand that is too low. there are some notes in the manual that say the voltage should be 7+ but, it does not...

Well that stinks. Good luck with the repair. Unplug the power supply and remove the top to see if you can anything obvious. Tom ... Good point... the only...

Dave, The 5 volts is really NOT 5V on the automation. No sense lines on the supply. The regulators work better on each fader is there is 7-7.5V DC on both ends...

Hi Tom, I didn't see anything obvious... which is why I'm leaning towards the thermistors on the heat sinks. I'll try that first and see if it brings ...

BTW a surge will not blow the transistors as the power supply is protected by a Corcom Filter. It also has over voltage and over current protection. Perhaps...

It's not too tough to figure out. The power supply should have labels showing the pinout with voltages for both connectors. You can use an ohmmeter on the...

Larry. The Peripheral Ground goes with the 24V. The Audio Ground goes with the +/- 18 V. The +48? I think goes with the Audio Ground. Remember the ground...

Possibly. You would see char around the suspect SCR. They are on the regulator board. If the SCR blew, It probably means there is a short in the console? Tom ...
