and you have suggested voltages that are spost to be on the grids of the output tubes? minus something or whatever it is? you can try unplugging the convergence and see if it goes up. one good thing to know about yourself is your are only a good as your test equipment to test yourself. you seem to invest in many lots of parts that are not bad and you could put that money into a scope and an eye type capacitor tester then you would have the experience and enjoyment of finding the bad capacitor. you dont need super fast scope or expensive because old tv shops going out of need to fix old tvs so they have lots of old things to test them.
you could find a way to put pictures in the site so we could have visual help you. if you look at your time as worth #5 per hour and you spend so many hours to replace capacitors that money could have gone to the scope to prove they were good before you changed them. i have lots of tvs and videos that i fix the tvs, you can view them and get an idea of problems like that. motorola had their own weird designs that were good but had parts that werent standard like couplets with the parts in ceramic chip with paint. i have black and white motorola i have been working on and when i put the couplet in the freezer the set is working now for several weeks. it could be the flyback if one of the parallel coils is open in the primary most of the time each coil in the primary has 2 or 3 wires tied together to handle the current if that goes open then the ability to carry current goes down it would be very helpfull to post the schematic for us to even if you have to go to kinkos for the scanner
