DuMont RA-112 TV: Next Project
#4

Simon -
My shop is the corner of the basement under the family room. I have to confess, the shelves are from IKEA. But the chassis stand is my doing. I need a proper workbench. I currently use a 37 year old wooden table from when I first got out of school. It works.

Gary -
The installed CRT is weak and has a brightener - not a good sign. The spare, supposedly tests good. Also, I know someone who has a good one.
I do need to order some HV caps. I think I have all the others (less mica which should be OK).
I have a converter or two. Also there are HDMI to NTSC modulators (need to investigate):

The plan is to first get the audio working via the FM radio. The problem with that is I'll need to free up the tuner first. It's not totally seized, but...

I also have access to a test CRT when it comes working on the video. I was warned about fooling with a real 19AP4 while debugging. It has a metal cone with ~13KV on it. Wouldn't want to get too close Icon_eek.

Can't think of anything witty.
