Acquired a former Zenith owned Conrac B&A monitor and Tectonic waveform monitor pair

[Electronic M]

So another member acquired a Zenith Radio corp owned Conrac CYB17 that I'm going to be repairing for them, and they let me know the person they bought it from had other ex-Zenith owned gear. That led to me purchasing this thing. The 9" CRT had a cataract that looked to be RCA style but was soft enough to cut with guitar string like a Zenith style cataract... either way it was probably the easiest cataract I've done where the entire face still had good adhesion. The monitor came up on the variac without issue thought one of the blue lytics looks quite leaky and was replaced. The other blue lytics also look bad but I don't have any spares so I'll have to order them with the CYB parts.
The Conrac had noticable burn in of SMPTE color bars(CRT looks weak buy I haven't tested it yet)...that and it's packaging with a video waveform monitor on the same shelf/bezel make me suspect this was originally part of a quadraplex VTR but I haven't found a model that looks like this would have been part of...
The waveform monitor was stone dead, but all that was wrong was a dirty power switch... Some of the controls are a pinch dirty but not terrible.
I need to figure out what to adjust the calibration square wave to for correct calibration.
The Conrac half is all SS except for the HV rect tube, and the Tektronix half has around 5-8 tubes and some transistors.

The manual available on TekWiki should contain the info needed to calibrate your Tek 529: https://w140.com/tekwiki/wiki/529

Nice find

Zenith never had a quad tape machine, but did have a type C. I remember a Conrac color monitor with color bars fairly well burned in after many years. It's very likely the one you have.

Edit: I see you meant the small B&W monitor has bars burned in - yeah, that too. It was probably used with Zenith's slide/film chain that was in standby most of the time.

The color Conrac has some color bar burn-in as well. Most notably the white square on the bottom and some darkened areas on the right. Emissions are still good though and it's the original Conrac tube which may have controlled phosphors, and was used in Zenith's lab, so I wouldn't change it. I won't notice the burn-in while I'm using it.
