Ok you guys would know this has a 21FBP22 in it not the 21FJP22 as listed in the schematic / sams , is this an older crt ? any advantage or disadvantages ? it looks like admiral date code 63-11
ok I will replace the caps in the vertical section as suggested , the set doesn't use 6GU7 tubes ,uses 6GH8 chroma bypass amp/color killer , 6JU8 chroma sync phase det killer det , 6GY6 z demodulator , 6GY6 X demodulator , 12BY7 Video out , 6EW6 burst amp , 6GH8 chroma reference osc , 6FQ7 b y amp r y amp , 6FQ7 horz blanking amp g y amp , that's the color board.
the jumped electrolytic that I mentioned had a hand written installation of 1979.

heres a question can I replace that electrolytic 160uf @ 250 volts with a 250uf @ 350 volts or a 470uf @ 250 volts or is going too high going to mess things up ?

he did something interesting , its a multi section can and all the values were connected together to make 140 uf which is 20 uf too low but it must have worked or was close.

what pin on the horz out are you referring to and if it is too high I have to change some resistor / resistors ?

oh yeah the .0082 @ 1000 volts could I put a .01 there ?
