Default HP3903A Manual OR Schematic??

Have me a 3903A gone flaky in the power supply... a manual and/or schematic would take some of the uncertainty out of the repair. Anyone?

The usual suspects:

eBay
Artek Manuals - ArtekManuals | Your one stop shop for out of print test equipment manuals
Manuals Plus - Manuals Plus - Test Equipment Manuals
You may be able to download a scanned version of the manual from Agilent directly. Search the Test & Measurement section.

What is a 3903A? Can't find any info on this. Agilent website has most service manuals online.

If you do mean 8903A, then go to Agilent website and download the 8903B manuals. The power supply section likely did not change much if at all, between the A and B models.

Oh carp!! I have surely lost what is left of my mind... I would have sworn it was a 3903A!!

Too many other older HP dist analyzers with the number 3 in the model number??

OMG. Surely I am lost in space!

Think I have to take a vacation or something. Phew. Bad. Geez.

Now to see if there is a schematic to be had or not...

<shakes head, muttering, walks off into the woods>
