Hi Chris,

It sounds like your situation is not so much different than mine -- various equipment that should do the job, but nothing that you've used often enough to really have confidence in its accuracy. I also have two B&K 1077 units that I could repair and try.

All,

I did a bunch of ringdown tests on various flybacks to see how they compare to what I'm seeing on the CT-100 flyback.

Here are the attached pictures in order:

1. CT-100 flyback, this time isolated from the circuitry (all connections removed, including yoke) - looks like 5 or 6 decent cycles only

2. Stancor A8134 NOS flyback, no connections

3. RCA 104309 NOS flyback with big coil, for 110 deg CRT (probably black and white), no connections

4. Traid D305 NOS flyback, for color set, no connections

5. Traid D311 NOS flyback, for color set, no connections

6. Traid D313 NOS flyback, for color set, no connections

Quite an obvious difference in terms of seeing a lot of decent ringing cycles on all the NOS yokes.

So that all looks nice and conclusive, but wait until you see the next post (I can't upload any more pictures in this one).
