I found a Stancor a-8122 locally, it's a vertical blocking oscillator transformer and has a turn ratio 1:4.2. Any one venture a guess if it'll work?

Should do the job. The turns ratio that is key to the magic that makes it work.

The only thing you may run into is the polarity (I suppose "phasing" is a better term since we're dealing with AC) - if it doesn't work, reverse the leads to one of the two sides and try again.

I don't know what would happen if you got the phasing out of sync here - If it's part of an oscillator, then it probably wouldn't oscillate, but since it's part of the vertical section, you might also end up with an upside-down picture (either way, it's a "safe" mistake - things won't go bang if it's wrong)
