RE: HP-65 1333A18516 - request for advice
Hi Alberto,
I'm not sure exactly what I am looking at, but obviously all signals are not present on the faulty unit, so I am wondering if the anode driver failed. That doesn't really explain why the signals ABCDE from the hybrid are not there though unless the anode driver is loading them down. 1V on VCC seems low for some reason, I suspect it would be higher on a working machine. I cannot test anything to clarify results, I was forced to move a few days ago and doing anything at the moment is rather difficult. Does the anode driver get warm in use? cheers Tony |
