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!)	Most readings are way off. Needs good overhaul or scrapping for nixies.
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.
