Some how I lost the URL for the site for HP discontinued product manuals. I just got a dead HP 209A and need to get it going. It appears that one of diodes near Q2 has shorted and toasted 2 or 3 resistors in the same row. Any tips or a scan of the ps board or a manual copy appreciated. tnx
I don't see it in the 'manuals' section on Agilent's web site, or BAMA web site.
The URL for the HP manual archive is

Thanks for the leads but I don't want to spend anymore on this thing as I will exceed its what it's worth. . The case is very nice and not beat up, close to new so I believed it was a working unit. WRONG, but I've been wrong before. I have a working 204C and schematic but the ps is just enough different that I can't use it for repairs. Something should show up sooner or later.

What do you need? There are only a couple possible power supply configurations. If you draw out that section of the circuit, and what the output voltage is, I'll tell you what the values ought to be.

Worked for me.. You have to be a member of the Yahoo group to get in and download files. Cheers
