I bought an HP 5087A distribution amplifier off of ebay. "The unit is
in good working condition". Funny the power supply is putting out 120
hertz square waves.....which makes all the outputs look like they are
oscillating garbage....disconnecting the power supply from the load does
not change the situation. I subbed a test power supply and the
amplifiers work fine.
Does anybody have the schematic to just the power supply and could I
bother you to scan it and send to me, or a link to get it, or the manual ?
The power supply looks very simple, but the schematic sure makes life
