Not really square 1, or square 5001. You are making progress...... I was just looking at the schematic & thinking about the hot focus coil too.... But I was wondering about the other part of the circuit....... You know, the part over by V1 where there has to be a rotten nut..... I'm wondering about C60, & R87, & R14. At this point any Variable Resistors should be checked from all 3 pins to ground for a possible internal short, not just checking to be sure they read their rated resistance.... I still did not see a post about R23 to be sure there is no short to ground from any of it's pins... Think about that "tin wiskers" stuff inside these pots..... Any way poor Timmy being pulled in 30 different directions to check this, and replace that..... I think he needs a beer....... And if he ain't drinking yet well then he's a strong determined individual! The other bad bunch-a nuts can be hiding in that V6 area, where this focus pulse is going - See that pin 3 with 2.5V on it, and with the scope pic of that 450V P-P wave.... No way you going to be able to figure out what should really be there..... And that little circuit helps that K1 do it's thing, and it's attached to V1, or did I say that once already..... .

unless there is some other weird error in the way the flyback was wired back up, I'm not sure what is going on here.

I would also think that C59 would be suspect, its getting hammered with pulses from the flyback.
DANG this set is REALLY an oddball one!

I still have the original 130pf 6kv and I have a 470pf 2kv and I have a 2.2Pf +25 pf 1kv coming sams don’t show a voltage for the 2.2pf I hope this cures L42 from getting hot that is very delicate.

Disconnecting the 470pf and 2.2pf made no difference L42 still getting hot and made no difference with video the 22ohm on v1 was 28+ohms so I changed the 22ohm on v2 it was 26+ohms on since doing this I don’t have the good video I had on pin 2 of v2. The batteries are at 8v maybe the subber is not working at full because of that. As for L42 all I got left is the focus coil or the 130pf 6kv cap which is new so I don’t know what’s more likely.

Has that big dropping resistor network been changed? r142-144?

I did not think that those caps in the sync/ AGC area had anything to do with the L42 heating problem, you unhooking them just confirmed that, the way they are doing things in this set is confusing to say the least, BUT, the current path for L42 has to be between pin 1 of the flyback and pin 8, and also the resistor network to ground.
But what is really going on here is odd.
