What do the "C=" microFarads represent?

It represents the self capacitance of the coil.

I thought that might be the intent but it can't be microFarads. Pico at least but even then the numbers themselves don't look right to me.

All I can tell you is what the test equipment displayed. I checked the numbers 3 times. Disregard the capacitance values if you want. The important info is the L, R, and Q. This info is 4 times as much as bobs data provided, or measure it yourself for your own edification. I tend to trust a 5,000 dollar piece of equipment. Math also works. Which I'm guessing is how these values are calculated. I will look at the math and se if it's way out of the park. As a technician/engineer I usually don't second guess my work unless given a reason. That is my .02.

Coil self capacitance for those coils couldn't possibly be more than about 15pF for the biggest one (and even that's a stretch).

Likewise, the Q will be at least 100 unless you used nichrome wire on a cast iron core.

However, inductance values seem spot on when checked against an inductance calculator.

I certainly meant no offense and have a healthy respect for expensive test equipment myself but even a Ferrari fouls a plug now and then, or maybe it's the driver, I don't know. But whatever the reason, those numbers don't pass the sanity check. It can't possibly be uF and, think about it, an 8 turn coil has almost 6 times the self capacitance of a 136 turn coil?

In the movies this is when the crew decides to disconnect HAL.

I have decided to remove the erroneous Capacitance data from my previous posts. It's not relevant, and it was an obvious error. The test equipment gave me the values, however upon further investigation they were suspect. On that note i have some pics of the parts i have acquired and the coils i wound. The values for the inductors are listed in a previous post.

Two more inexpensive single-ended audio transformers from AES are P-TF22921, 25000 to 8 ohms
and P-T1750A, 22800 to 8 ohms. They would be around 12000 with a 4 ohm speaker.
