We should congratulate Aaron also, from whom the recipe for a
dual-MOT ballast originated week on hvlist (actually, Carl did
mention that below, but I thought I should point it out again for
posterity's sake :))

Anyway, thanks to both Carl and Aaron for giving me something to do
tonight :D I just tried this with two *similar* MOTs, having the
same rated voltage and power capacity, and it appeared to work out
ok for a relatively small load (about 3A). Unfortunately, I'm an
NST coiler and hadn't done anything with these MOTs until tonight,
so I'm struggling to find a larger load to play with! Where's a
third MOT when you need one?! Time to go to eBay, methinks...
Safe TC'ing,
-Alex

Carl,
Congratulations, this may be the most important
discovery in quite some time.
I may be wrong, but from the schematic, it would appear that you
have the secondaries wired in parallel pairs of opposing series, as
you describe.
However, since the primaries are wired in pairs of opposing
parallel, it would appear to me, that the effect is canseled, and
you would in fact get voltage on the secondaries/controll windings.
Therefore I suggest that the schematic does not faithfully record
the setup as you describe.
Perhaps this is more what is intended?

However, a very clever idea. I have never seen anyone taking the
controll winding out on 2 separate
cores.
Cheers, Finn Hammer
