and we also see the effects..... So- this all leaves a hand full of parts that could be at fault,
or somehow way off in value, possibly switched etc. before you got it, since it's had this
problem when you got it.... I know you been looking at it for years, but it still leaves
the problem intact, so we're missing something.... Gotta check everything, even if you
take today off, leave it and do it another day.... I know answering questions like
"are you sure the fly is the right one?" is stupid.... But I Can't think of much else....

At this point I would have to be looking at circuit errors before you began replacing parts
and the errors may still be there because no one thought there could have been a
part in the wrong spot when you started this project....

ok so i guess when i pull the chassis i will use the sams and go over the fly section wiring including again what i did. and at one time when i found the focus wired wrong i did look around for possible mistakes both by me and maybe from others in the past but i didnt find anymore so at this point i dont really know where to start looking besides the flyback area and somewhat beyond that. i do believe to some degree that the hv reg is working but rather something is preventing it from working properly. so i will check the kine pot ohms again just in case i didnt check that and maybe i concentrated on the hv pot but i have alot to check now and until i find something concrtete the chassis will probably remain out of the set. i dont know if the horiz hold control being turned all the way at the time i got the set going and me tweeking the coil on the vert board to correct that range on the hold control would have anything down the line to do with any of this.
