Correct jamma psu voltages
bowza:
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:
fixed
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.
Cheers all
