I got an old HP 3466A (with battery option) of Craigslist ...40$. Pretty nice find; and now I am working to bring it back to life.
I have to say these things are pieces of art - I posted just for "porn" a photo of the gold plated PCB of the battery charger.
However, i dug (first day only) and I think I found the issue. Meter powers up, all nice, display etc but looks like the function and range switches are all over the place. I tested everything else and is in the parameters given in the service manual (7 volt logic circuits
and an micro working at a smashing 200kHz) .
So I got to the stage in which I believe the old switches are the culprit - actually i can see they literally cause buzzing and flickering when I push them. Parts are listed in the manual .. but fat chance finding something with that part number. Google blah blah ... nothing. I recon I am compete noob - how the heck these "selector switches" are actually called. they are simply listed as DPDT switch in the manual - how the heck are they called. And even more, does anyone have any idea where i can find something like this.
Attached are a few photos; any help is welcome
