This is the monitor in my Night Driver. It looks original, and history states that Atari used some of these monitors in their early B&W games. So I thought I would give info on it, as I was servicing it. It was working fine, but I at least wanted to service some of the POTS, check the B+ and recap it as the original NICHICON caps were on there and some were dated Feb of 74. 51 years and still going! That's a good cap manufacturer.
I checked the B+ at F101 and it should be 55 volts. (Red lead on F101 tab. Black lead on metal frame)
The tube it is hooked up to is a 22VATP4.
Pics are attached. I am getting a schematic soon and will upload it here. Any information in regards to this monitor should be added here. If I am incorrect with any info or there already is a repository of information, please don't be afraid to update.
