godfrey,
i think you're right, the big one has a 40-1 ratio and only shows about
a 1v difference between the small taps. it does have that hv totally
encapsulated windings also.
with an input of 120v the output is 4800v at some serious currents.

the little one must be some kind of filament transformer i would think?
it has a ratio of 16, 11, 8 and 6.75-1 with many combinations available
for different outputs.
both cores are really an oval more then square, but you're right in that
they are VERY nice.
i will see how cheap i can get them for a bulk type buy and if there is
enough interest, i could sell the transformers or pull the cores and
ship those? the small one has a core of 1.5" x 3", 11" tall and 6.5"
wide so 2 together would give a nice ballasting coil?
not that i enjoy the idea of boxing and shipping these up, but i would
hate to see them scraped.
thanks to all for the input on these,
marc
