Tube Color Video Monitor at Chicago Estate Sale

Those do look like PL-259 jacks on there alright. Is there a switch anywhere for swapping between 50 and 75 ohm input? If not, it may only accept a 50 ohm input.

I'll look to see if there is a switch. When I bought it, it had been connected to a Sony Umatic VCR with a BNC cable, with the adapter that you can see on the back of the set.
The two connectors on the left are for video, the two on the right are for external sync. There is a switch for internal or external sync.

The first TV Station I worked at (early 70s) had two of these Miratel Monitors. They were reliable and when properly set up made a very good picture. The UHF connectors are for composite video - the only thing around back them. Congratulations on a great find.

At the sale I noticed the back (I didn't see the rest of it) for a smaller (maybe around 14") Miratel monitor. It had the same design as the back for this one so it was probably from about the same time, but was solid state, and probably black and white.
I'm slowly going through the modules, checking the tubes and cleaning them up. I will need to order some new electrolytic caps for it once I go through and see what it needs. Most of the caps seem to be leaking some stuff out, and I want to replace them before I power it up. Luckily this set is too new to have any paper caps (that I've seen so far).

Great! I can't wait to see what the picture looks like. Lemme know if you ever get tired of it I'll come dispose of it for you
