Because of this thread, I chose a TS18 chassis set as my next restoration victim. This is a 7VT2, like shown here:
http://www.tvhistory.tv/1949-Motorola-7VT2.JPG This looks like a fun project, getting a little tired of doing RCA 8PT70xx sets and needed a change of pace. I verified that r-59 (Sams#) is indeed 22 meg and tests pretty close. Ballast is open, so I am working out a substitute. jr Last edited by jr_tech; 04-01-2017 at 08:14 PM. |

I have several of these 7 inch sets all hooked up and I seemed to develope these lines up and down on all the sets so I added an amplifier to the antenna and it cured it but just yesterday this one set got the lines back and have no clue what else would do this. All the others are crystal clear and all share the same ant line.

Does it still display the lines if it is the only set turned on?

All the other sets on lines are there and when they are off ,however I took the set to the beginning of the ant string, stronger signal and no lines but this is the set with the annoying hum in the audio so even though I checked the tubes for any heater cathode shorts, showed none but I'm thinking there is a tube in the IF that may have a short causing the hum as well as the lack of the set to operate with the signal that's there since the others work fine.
