I love wikis!
Hoping to help.
I was repairing something when I found your video - so I'm in!
Some stuff I'm working on:
| Type | Manufacturer | Model | Spec | State |
|---|---|---|---|---|
| DMM | Keithley | 192 | 6½ digit + GPIB | Mostly dead... It showed boot codes on display once - so I'm hopeful that there's not a lot to do. PSU rails seem fine. |
| Universal counter | Racal | 835 | 6 digit (nixie!) | Three digits not working. Building test rig. I'm impressed that this has a temperature compensated oscillator but also has external clock input. |
| DMM | Advance | DMM3 | 3½ digit (nixie!) | Maybe some switch contacts need cleaning. |
| PSU | Rohde & Schwarz | NGPV 100/1 | 100V 1Amp + GPIB | Visual inspection looks good. Will power up carefully some day soon. |
| PSU | Thurlby | PL310 Dual | Quad mode dual PSU | Visual inspection looks good. Will power up carefully some day soon. |
| CRO | Gould | OS1400 | Dead. It worked and stopped! | |
| CRO | Tektronix | 2465B | Calibration data backed up from Dallas SRAM module. Needs PSU rebuild and re-assembly. | |
| CRO | Tektronix | 468 | Needs calibration and balancing. | |
| CRO | Tektronix | 465B | Needs calibration and balancing. Focus pot very stiff... | |
| CRO | Telequipment | D83 | In pieces, ready for careful power up testing | |
| CRO | Telequipment | D75 | In pieces, ready for careful power up testing | |
| CRO | Telequipment | D67A | Ready for careful power up testing. |
