They list it. I know nothing about them.

If this is the chassis I am thinking of it has a SMPS with 2 ceramic modules.
They went DISCO in the 90's. There are 2 'lytics in the HV in series. One
is the HV filter the other the 200V filter for RGB outputs. They went &
are near the FBT. Try them first.
The supply should put out a solid & clean ? 130 ? VDC. There is
probably a marked TP for it. BTW If the modules go usually the set goes dead.

thanks for the replies. i did find that website with service manuals but they are long gone.

i've attached some pictures. the vertical board has a test plug that's plugged in not sure how that works.

the tv picture looks great outside of the distortion.

i'll see if i can check some voltages.

the yoke is up against the tube.

Chassis # A7R-42000
