Title: HP/Harrison 6438B DC Power Supply, service manual
Post by: valvedoctor on June 27, 2017, 02:04:42 pm

Hi All,

I have an old HP 6438B DC Power Supply, great bit of kit, but it has excessive noise and some of those old caps have to go. All carbon composition resistors as well that are drifted.

I didn't want to shotgun this one, I'm looking for the manual, with no luck on google, except for a partial one with no schematic, no good.....

Does anybody have a scan they can hook me up with?

Thanks in advance,
ValveDoctor
