I'm working on this Berzerk board and I'm stumped! There is no 5VDC on the power supply.
I get the other voltages. +12 and -5, but no +5. I checked the +5vdc diodes out of
circuit and they're fine. I changed the 5vdc filter cap as well. I also used a ESR Meter
to test all other caps and they're fine. Still no +5vdc. What could possibly not generate
+5vdc on this power supply. It's a simple supply. Turning the +5vdc potentiometer does
nothing. Any ideas?
 
how exactly did they mount the boards in the cocktail?

also, you probably have a bed regulator.
 
It's in the "bottle cap" type transistor packaging....probably mounted to a heat sink of some sort.
