Hi Folks,
I bought a used HP 66311A DC Source. The voltage output is perfect however the current is limited to around 0.600 amps. I tried to recalibrate the current values, any attemps to program come back with "out of range". Also one of the 15 volt regulators (can't remember which right now) runs a very high temperature - too hot to touch after a minute of warm-up time and no load present. I have a feeling the "Shunt Clamp" drive circuit is the culprit here. I cannot afford to send it in for repair, any suggestions? It's the through-hole board. Anybody have a schematic diagram of the unit? Thanks!

66311A was introduced in mid 1998, obsoleted in 5/18/2002 (replaced by 66311B), and was "out of support" in 9/30/2005.
Being part of the rapidly changing/evolving cell phone testing/mfg environment, no schematics (and virtually no) customer focused repair information was created.
Unfortunately, even if returned to Agilent for repair, it would be a 'best effort' situation.
