CJ said:fantastic! been waitin to see that pic for about 100 years now!
that core has wax between the lams which is stuck real good at room temp, so gently bake that thing at about 180 F or maybe 200 F if need be, and the lams should slide out, try not to bend them up as you can lose inductance,
can you do a quick inductance check? is there a good primary or are they booth cooked?
if not, connect a sig gen at 20 Hz maybe 10 volts and see how much current the coil draws,
can you take some more pics? like one from the sec side and maybe one from the top so we can see how shiny that core steel is?
thanks, you are the man! maybe take DCR readings from good coils, measure wire size with calipers,

shipping to USA is very high cost for a transformer like this...
CJ said:yes, since inductance is turns squared, and impedance is turns squared, the ratio for one is the ratio for the other, in an ideal world.
you do not have to take each lamination apart one at a time, you can simply heat up the transformer and pull the coils apart, the core should split in half because those are L lams.
then you can pull the lams out of the coil, try not to bend them as you break the crystals and the permeability goes down.
CJ said:just a thought, look for pins in the lam holes, sometimes they stick wood or metal pins in there to hold the core together,
CJ said:check the holes in the core stack for pins by pushing a 1/2 watt resistor lead to verify that the holes are clear before you try to pull the core apart,
Hi Opacheco, I tried to PM you regarding S-217D but your box is full. Can you please contact me by mail? (please find it inside my signature)opacheco said:Ok....although they look like very, very clean inside, I can see the light thru of them and they don't have any obstruction at all.
Opacheco.
