[Collins] Wanted: tuning slug for 75S-3

[Bob and Sue Jefferis]

Jerry,
I found one! It came from a basket case 75S-3B and it still had the original parts ID on it. It bears 2 part numbers and a date code. The part numbers are 526-5007-001 and 288-2214-00. The latter matches your reference. I suspect that the 526- may relate to the top level assembly, i.e., the receiver, not sure. The date code is 6552. Anyway, I am back in business and will soon have this RX in service. Thanks for looking at the later manual.

73, Bob KF6BC
