thats all for tonite, I checked the .001 2kv elmenco on the primary of the vert out, value right on, no fuzzyness, no leakage at 450v (which is high as I can go). I would have replaced it anyway, but I only have some dipped that go to 1.6kv, so I will have to order some of those (I dont trust them).

there was a single black plastic .01 400v sprauge in the horz osc section, it tested perfect, no leakage at 450v so I left it alone.

I am trying to not make too many changes just in case I goof something up, it was working after all but for the horz AFC.

I did check the vert osc bypass cap a 50uf 150v, tested perfect again I left it. I randomly check a few of the purple dipped caps a .47 and a .1 both 200v, they checked fine, no fuzz no leak so maybe I will get lucky on this set and dipped caps.

that bumblebee across the line was fuzzy and very leaky, I am suprised it had not blown up yet.

I did have one open cap, a 100uf nichicon 25v that I think is part of a degaussing circuit. I see a diode and a relay all tied into that blown large VDR that is around the degaussing circuit.

looking a bit closer, that relay goes to the B+ circuit breaker, so my guess is its a delayed B+

popped for a full set of electros, about 35$ got that 2k vert out cap, and a new line suppression cap. This weekend it will be just the strain reliefs and the AFC, now that I have the caps on the way I will have to wait as I dont want to have to reinstall just to check it out. I really need to get my test jig installed in the shop.

I got all the caps from mouser, all radials, will stuff cut off the cans and leave the base in place, use a bone saw to do the cutting.

I will prob check 1st, if the 450v's test ok I may just leave them.

I may have the HV cover for your set. I parted out a magnavox console a while back. Your chassis looks like my parts unit. You can have the HV cover.
PM your address and I will send it to you.

Got the horz AFC diodes in, I think I will spend some time tomorrow cleaning the crud off the PCB's really dirty. Gives me something to do while waiting for the caps. I seem to get a lot of sets with defective horz AFC diodes, whats the deal there? most of the other diodes always seem fine.
