Hi,
I'm trying to cobble together a tuned input and need the value of a fixed inductor (Thumbnail pic) from the Tuned Input of a Collins 30L-1 HF amp. Every Collins diagram / manual I can find list is too blurry to read. Part L-19

I tried to decipher the color codes but I can't figure it out. there is more than 1 color code scheme for fixed inductors yet none of them seem to fit. Either the color is not listed or the value in that column is blank.

It's plainly a 4 band marking and I suspect the fat silver is Tolerance leaving: Brown-Gold-Green. My cheapo inductance meter wont read it (time to upgrade but there is a large price jump between the cheap meters and next level up). Until then, is there something I'm missing about interpreting the color codes or does anyone have knowledge of the 30L-1 fixed inductor in the Tuned Input (a longshot but there's only 1).
