A few days ago my wife and I drove down to the Chicago area to buy a used 19AP4/ Dumont. The CRT was a dud, had a cathode-filament short.  The trip wasn't a total waste, ended up buying some old radio and television tubes.  |
If the short is the only problem, then get a CRT heater isolation transformer....They are in the same packaging as brighteners (some units did both operations). I may have a spare tucked away somewhere.
