Philco 50-T702

On most of theses electrostatic deflection sets (ones that use 7JP4's and the like) there are several high value 1/2w resistors connected to the HV/focus control. They are always way out of spec. Cause poor focus issues. duh
The 6kv defection caps should be replaced with mylar caps. You may be able to find ceramic disk caps but they tend to drift in value (heat up) do to the presents of rf energy and cause issues.
Looks like it's coming along nicely!

Terry,
Yes, all of the high value 1/2w and 1w resistors will be replaced before power is applied.  The 6Kv deflection caps are being replaced with a high quality ASC X675-.0047-10-6000 tubular axial caps.  I'm still tryin to get the same caps only in 2Kv and 2 different values for the other 1Kv and 1.6Kv caps.  I have some Panasonic "Chicklet" brown caps on order to replace those if I can't get the ASC brand.

There will be no ceramic disc caps used.

Thank you.

Tonight I started to remove the all of the E-Caps that are in cans to prepare them for re-stuffing.  My E-Caps should be here tomorrow for the cans.  I'll be busy for a few days doing those and getting them back into the chassis.
