I bought a HP 3469B with the dot-display from about 1974 and am waiting for receiving it. Unfortunately it comes without manual. I downloaded the manual from the keysight website, unfortunately it is a very bad spotty scan which makes it nigh on unreadable in parts. Does anyone have a neater pdf available and would be willing to share it? I intend on taking it apart and cleaning it when it arrives, it seems some capacitors might be at the end of their lives. "DC measurement works but takes some seconds to reach stable value, ohms take some seconds but then the values swings wildly, AC untested"...
I'll post pictures (and probably questions) as soon as I have it in my hands.
Best regards
