Cant seam to bring anything up in a search so ill ask

What are the correct voltage ranges for the 5 12 and -5 outputs of a jamma PSU

Mine reads 4.9v 11.8 and -5.07

Thanks

Bowza

cholin:

They seem fine.  As long as theyre really close to their voltages, its fine.  Are you having problems with it?

bowza:

I have a system 11 board soul edge that graphics smudge , thought it may be voltage related as a taito Cartridge board works fine, also a standard jamma board works ok.

Thought the system 11 may be less low voltage tolerant

Thanks

Dave

RayB:

graphics SMUDGE? What does that mean exactly?
Sounds more like a monitor problem.


bowza:

Replaced psu with one borrwed from the guy I bought the monitor from , now a nice crystal picture, so off to find a nwe psu next.
