[Collins] Early 30L-1 amplifier data

[Bob and Sue Jefferis]

Greetings all,

I believe the 30L-1 amplifier input tuning network underwent some changes early in its history. I wonder if anyone having first, second, or third edition 30L-1 manuals would be willing to share schematic and part list data with me. I am interested in the published values of C60-C69, C75, C76, and detail of L14-L18, i.e., the number of wire turns that might be shown in the parts list. 

I am aware of ASAB 1008, but I suspect the original, or very early input pi network components may have differed from the "before" values one can infer from that ASAB.

Happy New Year
