Tony (among
others) has given good info on tube repair in the past.
Talking of which, has anyone got any hints for rebuilding defective
CRTs? It seems like some madman on this list would have a vacuum setup...
The general rule among people I know is LEAVE THE TUBE ALONE. If you have
two units, one with a bad tube and one with bad electronics, move the
electronics, not the tube. etc etc. Handling a CRT is just too dangerous.
