Thanks for the information on finding those capacitors, for a long while I couldn't order anything because the mail delivery here is awful, and stuff would always go in wrong peoples boxes, get lost, and anything that wouldn't fit in the box just got returned to the sender. But I finally went and got a PO box, so I don't have to deal with that mail delivery awfulness anymore, so now I can order something and actually expect to get it.

"They may also have the high wattage resistors you need to make a ballast replacement. I used Dale type resistors on a little copper board. You can read more about that project at:http://antiqueradio.org/motvt73.htm"

I enjoyed reading that, I had been debating how to place the ballast resistors, and I liked that piece of metal ontop of the chassis, and then plug them into the ballast tube socket idea you had. The last one I fixed was unsuccessfully converted to filament transformers by a previous owner, rather than stripping the rather extensive modifications out, I managed to finally get them working as I think they were intended to, but it was a real mess to sort out and I don't want to go through that again. Also that arcing crt socket made me think that that 1 crt I have might not be arcing inside the tube, but maybe inside the base, I know it's not the socket, because it doesn't do it with the other 7JP4s.

All 3 of my TS-4J chassis are 1948, the one I fixed previously with the filament trans. is not copper plated, the other 2 are copper plated. I think there must be alot more of these 7" motorolas out there than there are good 7JP4s left.
