Motorola 12T2 Restoration Restart

[Winky Dink]

Since getting the B+ voltages back to normal, I ran the voltage chart again. V1 through V17 looked pretty good. But when I got to V18, pin 8, which previously showed the appropriate 380 volts, now overflows my 600-volt-max multimeter. I tried again with a 1000-max-volt multimeter, and that one overflows, too. In both meters, the resistance/capacitance sections are fried. But they still work for AC and DC voltage.

My first thought was to throw the set out the window. But when I calmed down, I rechecked every connection that I had recently worked on and over the next few days rechecked components, transformers, resistance everywhere, and I found nothing wrong. Nothing wrong except having over a kilovolt at V18.
resistance/capacitance section is dead. The second meter also acts funny in the resistance area.

Other observed changes are that I get no noise through the speaker and cannot hear the flyback anymore.



Here’s another observation: It’s not good to turn on the set when the HV rectifier cap is not connected.



I’m a bit frustrated, so I put a time limit on this project. If I don’t get a raster within the next ten years, than I’ll think about quitting.

Please, what in the world should I look for to resolve the too-high voltage issue.
