This is a Volcano machine from CraigsList, history unknown.

I tested the output of the rectifiers inside the cabinet, and here's what I found:
12.7 from the one labeled "12 VDC Power Supply / Sound Board"
6.8 from the one labeled "6 VDC Lamps"
39.5 from the one labeled "38 VDC Non-controlled solenoids"
36.5 from the one labeled "24 VDC Controlled Solenoids"

The first three seem close enough for government work, but the last one bugs me. The input reads 30.3 VAC, same as the "Uncontrolled" one. Is this proper and expected, or is there maybe a short in the transformer?

Perhaps not coincidently, I'm having voltage problems with the sound board power supply (see my other post, http://forums.arcade-museum.com/showthread.php?t=166186). Could these problems be related?
 
check pinrepair.com about voltages
unregulated voltages ones can be off a lot when you measure them without a load, you shouldn't worry about those - so I would say they are all ok even the 24v

only the +5 and +12v need to be correct when exiting the powerboard, but if both leds on that board light up they are ok..
