"By coils, you're referring to the coils on the neck board attached to the RGB output transistors, correct? It's weird, but the service manual and the Sam's both give different values for them, so I'm not actually sure which they should be. I could pull them and measure them. I have an LCR meter. The Sam's says 1.5uH, the Sony manual says 8.2uH. Go figure."

I mean any of the six coils that are the same in R,G, and B: L702, 703, 704, 302, 306, 307.

I just noticed that C701 (blue channel) is 560 pf and the correspong R and B caps are 390 pf. This could be making the difference, though I'm not sure why they would do that.
