Two CRT's have leaked slightly, what's the best way to "seal" for the leak? Regular household RTV silicone? Pinhole in one 2nd anode at the CRT, I have anodes, what type of high voltage sealant is recommended? Thanks, Rono.
We use a very thin layer of pure silicone RTV sealer to seal the coolant chamber. For the anode lead you can use the same, but several maufacturers have anode lead sealers. We still have a few tubes of sealer that one manufacturer used to provide with CRTs but it does not have a number or label on the tube. Maybe someone here remembers the part number for one of the manufacturers. The main thing is to make sure that the crt and the lead and boot are clean and dry before assembly.
Good luck with the circuit boards if it got to them.

Yes, it absolutely needs to be 100% clean and grease free before applying the silicone. Yes, the silicone needs to be 100% cured before applying power. Usually 2 to 3 days will do it, but be on the safe side.
I think MCM Electronics still sells the smaller Philips HV rated silicone tubes.
