Hello, this is my first post, and thank you for adding me to the group. I've just begun poking around a little and I can see that this group is a great resource. After I retire I might have time to restore the three antique radios that I have, one of which was my grandfather's.

I just purchased this 865B power supply for my home lab and am looking for a schematic. The first step will be to recap it, and I suspect that may be all it needs because severe ripple is appearing on the output. I really like to have schematics for all of my equipment and am a little surprised as to how little information I've been able to find, especially since I found a great article in the July '62 edition of HP Journal describing its design innovations. This little supply was ahead of its time. Can someone steer me to a site that might have the schematic, or does someone have a schematic they can share? I managed to find a 6266A manual with schematic, but it doesn't appear to be very similar. Thanks!
