[Heath] Value for Heath 46-65 inductor ?

[Wilson Lamb]

0.3mH wouldn't do anything at audio freq. 

It's more likely an RF choke, likely operating at several MHz. 

Its Z is 18K at 10MHz, if I didn't slip a decimal point, plenty high for an osc or RF amp. 

What's it doing in the circuit? 

Picture??

If I am reading the 1984 Master Parts File correctly it is an AF Choke .3 Mil H which would be 300 microhenry.

Does anyone have a list to show what the inductance value is / was for a Heath P/N 46-65 inductor?  I don't know what model it was in, and that is sort of moot because it was used in a custom design audio low pass filter that was not an H product.  My guess is that it is in the 150-180 microhenry range, or at least that looks like it is what it could have been by my modeling.  Thanks and 73.
