Zenith 25EC58 poor focus

[Electronic M]

The safety caps are either.018 or ,0018uF....I believe the latter but I don't have the Sam's I read that off of in front of me.

All CCIIs have a focus control. Have you tried adjust it? If it's at one end (I presume you have it set for minimum voltage and best focus) one of the resistors may have drifted.... Often the HV divider resistor (which is often part of the trippler) has drifted...if the special HV five resistor has drifted you can often unhook the end of the focus pot opposite of the end the wiper is on and insert 1-15Meg ohms (it'll take some guess and check work) worth of 2W resistors between the pot and the lead you unhooked from the end of the potto move optimum focus voltage into the middle of the pots range...I try to never add more resistance than the pots max resistance to the string in one go. If the focus gets worse despite adjustment you choose the wrong end of the pot or overshot the value.

I've done this on trippler sets and on the older 12B13C52 hybrid chassis that have the giant ceramic HV divider resistor. With success and it has lasted years.

The video issue I haven't seen in my sets.
