2nd type of inductance test, hold pri volts constant at 20 V-rms and vary frequency while tracking excitation current as to plot Henries vs Freq telling us about the core,

Uncle Doug? does he do the Dougie?  no not here in Kentucky.

rewind done, lucked out with wire DCR is on,

Henries shot up from 50 to 160 H due to the rotten primary wire which broke many times upon unwind,

wire colors have been adjusted from grn to blu, red and yel not org and org,

not much difference in square wave response after the varnish dip except at 100 K Hz,

looks like the Laplace Transform has caused the dialetric of the varnish associated with the Fourier Series to be tilted by 37.5 degrees centigrade,
which will roll off a high C at 65.8  mega hertz, given by  y(t)=A e^{{ t}} + t (cos t)+sin(t ),
