sick '70 power supply?
I've got a 3670 that upon power up does not turn off its fault light. I
noticed that the main -12v light on the back back of the machine was not
lit, though all others were lit. I don't know if the bulb is burnt out
or if indeed there isn't -12v. On checking my powertec power supply,
model 6JA5-BBF-17, all the channels were normal except channel 3, which
was putting out 1v instead of its labeled voltage of 12. The
machine was fine this morning. I had to power it down to do a board
What is the minimum board set one could put in an OBS machine and
have the fault light go out upon power up?
Can I adjust the voltage of channel 3? Or, is there a fuse or breaker
that could have tripped? Or, do I need a replacement power supply?
Thanks for your help, fellow sluggers.
