CRT Rejuvination tips and tricks

[leadlike]

Don't forget to tap the neck to try to clear any shorts that pop up on the tester...

What a lost art this is. I wonder what the crt engineers thought of testing/rejuvination and all the black magic that goes with it...

We did that. One of those nothin to loose deals, often worked good.

Along with adding a winding to a flyback supplied filament
there is also usually a low ohm resistor in series with the
filament, jump it out. IMHO also last resort but effective !

Sears / Sanyos with Sylvania CRT's that H-K short.
Anyone remember the mod ???
IIRC get the filament above ground, add a 1.5 meg from the
filament to the shorting gun. Also add a .001 cap to ?
Saved a crap load of sets, also worked on others.
