These perform very well. It is stuffed with wax and other types of capacitors that leak especially after 63 years! Replacing these will sort most of the problems. Start with the line output stage, follow on to the frame timebase to get the raster correct, checking as you go then you can move on to video, I.F. and sound.

The Mazda CME141 tube is very reliable and the same goes for the LOPT which in the V350 is an open type, no nasty oil to deal with.
Regards, John.
