Need some serious help with MK2 sound
Malenko:
Where do you live? maybe someone local can let you test their MKII in your machine or let you test their MKII in your machine?
does the game pass all the RAM/ROM checks?

I live in langhorne, PA about 20 minutes north of philly. All roms pass and when i check in the sound board test, that passes too. I dont think its the board since everything works other then the hum but i dunno.

Check this older thread might help.

Yeah i read that thread already but thanks for the help! I think i found out the issue here. I was testing with the multimeter i have and realized that when i turn the voltage knob on the power supply that the voltage does NOT increase or lower. It is always set at -4.99 volts for the audio wire. I think if i get a new power supply and turn it up a bit it "should" fix it. Keep you all posted!
Malenko:
I'm in Newark,Delaware not too far away if you wanna make the drive I have a dedicated MKII cab.......
but it does sound like a voltage issue.
