I hadn't watched this set since January. Then last night I went to turn it on, and the sound came up, … but then no picture and the sound of something arcing
The CTC-10 I used to have did this once, and it just turned out to be that the wire wound around the flyback to supply filament voltage to the HV rectifier tube had a hole burned right through it. I'm hoping it's the same problem, or something similarly easy to fix. I have next week completely free, so I'm hoping to fix this and at least get started on that Admiral 17T12 I picked up.
