RF coils/transformers available

[JOSE V. GAVILA (EB5AGV/EC5AAU)]

Hello!

I have some adjustable RF coils/transformers. They are NOS and have a
Heathkit reference written on them. There are some different models. The
coils are about 1.5" tall, 1/3" diameter, and have an adjustable ferrite
core. There are two different mounting types: panel mounting (without pins,
but with a metal piece to fix them in a hole) and other with pins (from 3
to 5, depending on models, as some have double winding). Some have a
capacitor in parallel.

Here you have some of the references and mount types. I have multiple units
of each:

Ref.     Type     Windings
40-577   pin      1
40-578   pin      2
40-964   panel    1
40-966   panel    1
40-1027  pin      2
40-1028  pin      2

Some of them have a date stamp of 1966.

I wonder if you know where they were used and also if there is anybody who
needs any of them.

Thanks!

Best regards,

JOSE
