Admiral 21F1 HV issues

[bgadow]

The trap wouldn't kill the HV-I mentioned it because I have had sets before where there was HV but no raster-and I kept blaming it on the HV.

Sencore made a very handy tool for diagnosing these, and I suspect other companies did as well. It features an adapter that plugs in between the HO tube and socket, among other things. It will measure HO current and can also interject its own horiz osc frequency. I use mine quite a bit as it helps pinpoint where the problem is. If the HV will wake up with proper horiz osc. applied then you know which circuit to target. I think the B+K TV Analysts can do this as well, if you know what you are doing.
