This is a good idea, IMHO. I had looked into using a GO-7 HV transformer as
the basis for a new HV supply (not the cheapest, but readily available --
seemingly forever-- and I had all the "parts" needed on old GO-7 chassis).
I quickly realized I was in over my head on the analog side though and kinda
abandoned the idea.
The gotcha with picking a "cheap" HVT from MCM is whether it'll be cheap
forever. (Sometimes the cheap ones are just getting sold off.) I also have
*no* idea where you'd get a "designer's guide" for a particular model HVT.
(I didn't know how to spec the boost transformer from a new supplier--
robbing them from old GO-7's is only good for a while...)
Since most all the color vectors use the same tube it seems that a common HV
supply would be very do-able.
I wonder if there's such a thing as "several" HVT's that have common
footprints and at least "sorta" close specs? If so it'd probably be
possible to do a single PCB and then have different stuffing options for
more than one transformer in-case one were to "go off the cheap list"...
