Anyone have one of these? And perhaps seen the service manual for it?
Apparently this device had taken a "faceplant" (I saw this term used before for bench equipment, and all I can say, yes, this device did take a faceplant) and someone had started parting it. I wonder if it's worth to repair it. I think I got the dual controls working again and does not seem to be any damage to the meter, but too late - noticed the op amp/control board was partly gutted - all the transistors were swiped from the sockets from the board
Even one of the TO-3's were desoldered...
And a lot of the caps look like they're shot. Dang 60s caps.
Unfortunately this thing probably had a lot of germanium transistors which is likely unobtanium now. Maybe some mods are in store for using silicon transistors...
This thing seems possibly useful for testing other stuff as it can go up to 40VDC, which I don't have any other PSUs that can go that high. It is a series dissipative design so likely it gets quite hot.
Restore? Or perhaps I should make a new circuit board with LM741s or something and really redesign it more like a 6226B with silicon...
