DuMont model# RA-166

[cademan]

Hi, I have a DuMont 1953 tv which has been sitting in storage for at least 25 years. I finally got to it to see what could be done to bring it back to life.

I didn't turn it on before I did a recap but after the recap, it came to life. No smoke or anything bad, just great light and raster, full screen and excellent vertical and horizontal sync.

Problem is that it is not getting any RF. All tubes test great and the sockets have been cleaned, just no RF.

I know I can get it working and I am not giving up on it just yet but I thought maybe someone here might be able to give me a few tips on where to look.

I haven't found any open resistors or cold solder joints. I could test for B+ but I just haven't had the time just yet to really dig into it so I thought I'd see what people here had thoughts first.

I have the schematic and have been studying it for days but nothing is really jumping out at me so I thought I would ask here for some tips before I really dive in.

Thanks for any help and support.
