I would think that whatever color sets of the late 60's/ early 70's did not use triplers and their flybacks put out the 25 kV+ by themselves would be the ones I am looking for, without the built in rectification of course. |
You have some misconceptions about your old failed supply....your burnt up flyback was not a type that was meant to use a solid state trippler. It had a HV rectifier top cap connector on it so was a tube rectified type...by around 72 most makes had switched to tripplers in their solid state and tube/SS hybrids. Most makes stopped selling sets with tubes by or before 1975.
Using a trippler with a non-trippler fly like that will either short the trippler (they will sometimes straight rectify their input when they short and could feign normal opperation while loading the fly to death in such an application as a home brew power supply), or require you to drive the flyback much less than normal and possibly have lower current output.
If you want more than 1mA it really would be better to get a modern or even used neon sign transformer (last ARCI swapmeet I got a used one for $1) or something similar.
Also it can be hard for us TV collectors to find the flys we need...It would be better for future maintenance of your supply and for the collector community if you considered something else...
