No line transformer near the CRT.

Tomorrow I should have my HV probe for my VTVM. Only then will I know what kind of HV I have.

Cool! The probe is the Knight-Kit probe for the KG-625.

It looks like they broke flush...
If you can CAREFULLY chip enough glass away from the leads to have something to solder to then you can use the really fine phono hook up wire Rat Shaq sells toconnect to the stub....I've had success with that method, but it takes a high watt iron and speed to get a good joint, without cracking the glass.

Dangerous to your CRT! Do it right ... go to store like Lowes or Menards and buy a nice, new DIAMOND encrusted tool of suitable shape. I used a cutoff disk. And use it BY HAND. Slow but safe. However those wires look very close to being long enough as is. If they stick up at all, they are long enough. Clean them with #0000 steel wool or fine sand paper. Tin them. Then solder on tinned #30 or so wire ... I get it from #22 tinned stranded wire. Finally stabilize them using sensor-safe silicone. Make sure they are long enough to go throush the base pins. With ordinary care, your tube will live just fine. Don't worry about breaking an extra wire ... I broke a filament wire on one of my 5BP4s fixing a broken deflection plate pin, and it works fine. |

Thanks guys for the tips on fixing this CRT. Seeing it does test good with the wires hooked up I'll try and save this thing. Stay tuned.

The Focus wire could probably be fixed with some conductive glue (rear defroster glue for instance) since it carries little current, the heater otoh will probably need a more direct connection.

Nice work. The coil method for the new wire is what I do too.

I added a 10 ohm 25W resistor to the filament string. The filament string is for 115vac and my wall outlets provide 124vac. I thought that the 124vac would be a bit too much for the filament string, hence the resistor. The filament string is now at 117vac using my wall outlet. I used such a big resistor because I had one on hand and also I like to way oversize these things.
