Yes, I see.
I never attempted to get the laminations apart. Using a hacksaw blade, I
cut the secondary turns and drove them out of the core with a punch.
Next, I used teflon tape around the core for insulation, and wound the heavy
thermaleze insulated wire though the windows in the core to complete my low
voltage winding.

Regards,
John

I have missed that. What are the problems?
Even the power supplies I have made which power 1500+ liners have held up
fine. I do notice they seem to run a bit warmer than their expensive
counterparts.
I am convinced without arguement that their efficiency is lower than a
more
conventional xfmr--one reason--microwaves are usually only in operation
for
short periods of time.
However, all I can see which might be happening is my electric bill is a
few
cents higher...

I couldn't get the laminations apart because of the welds. I would go
down to the garage and chisel away at them every couple of day, but I
finally gave up. My intended use was a hi current 13.8 V supply
