I purchased a transformer with the following advertised spec.
"100-Ohm CT to Dual 1.5Meg-Ohm audio Transformer"
I have picture with the data here.

I need a couple of things cleared up.
First I note two separate 1.5M windings for ZL.
The Zs has a CT. 100 ohm winding.
Does that mean 100 ohms from pin 1 to pin 3 or pin 1 to pin 2?
I suspect the 1.5M actually means 1.5K ohms because I get no where near
the 1.5M ohms I expected. Is that possible?
I'm measuring at 2 khz.
I see the 1.33 x 10^-6 watts ratting, I think that's tiny,
any possibility the 1.5M ohms is correct, I'm just overdriving the
transformer.
I have a nice signwave in and out.
I was hoping to use this for a crystal radio as a high impedance load to
the tank/diode circuit. But I don't think I got what was advertised.
Any advice about how to test this?
Thanks, MikeK
