Quoted from Doggy:

I have a problem with my system 1 rottendog power supply, while testing the 60 volt pin my hand slipped and I inadvertently hit either the ground or the 42 volt pin. It gave off a little spark. Then I had no voltage coming out of the 60 or the 42 pins.
I installed a new HV regulator LM317AHV and now I get 58 volts from both pins.. could I have fried something else when my hand slipped?? I can’t adjust the voltage like you can with the original power supply. Any suggestions would be appreciated..

Quoted from Doggy:

So those of us who invested in the rottendog PS, which regulator would you suggest when/if the LM317AHVT malfunctions? Also if we change out the LM317AHVT regulator, is there other components you must change also??
I know the obvious answer is stay away from the power supplies which use that regulator, but if you already have it what would be the best modification??

Thanks German-pinball I have 2 system 1’s. I will buy a couple LM317AHVT just in case. But for my future projects I’ll stay away from those power supply’s that use the LM317AHVT regulator’s thanks to you and G-P-E for the heads up.
