Adjustable coils available

[JOSE V. GAVILA (EB5AGV/EC5AAU)]

Hello gang,

Some time ago I bought from the Net some (about 75) adjustable coils. 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 are used and also if there is anybody who
needs any of them.

Thanks!

Best regards,

JOSE
