RCA CTC...Something? poor HV output.

[zeno]

1) bad focus rectifier gives bad focus !
2) your pix bright, full width, does not bloom.
The hoz osc, out, damper, rectifier, focus rectifier, HV reg
are all good. Your meter is NG, try it on another set.
3) arcing at the HV rect socket usually the cup. Other 2
wires are the filament & wrap around the FBT core.
ALL the wires are at full HV potential. & can arc anywheres.
4) Try a "by the book" grey scale set-up. then turn you attn
to the 6GU7 area of the set. Watch for dried up wires, they
were common even 45 yrs ago.
5) put up a few screen shots that show people & colorful scenes.
A pattern is fine but a real scene shows more.
6) the old pixs looked AWESOME so unless the jug has aged
fast & it happens, you will have a great set.
7) so you have 3 problems. Vert, arc & poor color. You should
get a first generation Sams for this set.
