Coil is similar to Miller number 70-OSC oscillator coil. Their small physical size and the fact that they can be adjusted to the inductance required make these coils ideally suited for replacement in broadcast band receivers. The 70 Oscillator coil has a primary and a tapped secondary. These coils are for use in all common padded and unpadded oscillator circuits.

For the R.F. stage coil see P-C70-RF

Worked on a 1937 radio

Buzz1151 - March 12th, 2019

Exellent gain, this osc. coil works good in Am/mw mini transmitters as well as being a good coil for regenerative radios.

Mice got to the oscillator coil in a Magnavox CR-216 chassis. Used this as a replacement and it worked just fine. No trouble with alignment.

All of the products I have bought over the years have always been top notch, work as expected and has the right value.

Terry Hobbs - April 4th, 2018

I had multiple failures in these coils, several have brokem while I assembled my device and another while I adjusted it.
In addition the allen key adjustment is Difficult to adjust with standard tools, because the metal in the allen keyeffects the inductance of the coil.

This item worked perfectly on a Philco 42-PT-7 that I am restoring. Very satisfied.

It is fragile & not well made you should find some other sources

Made a great replacement for my AM Transmitter.

David DeRosier - May 29th, 2015

These coils are great. They are an excellent replacement for tube type local oscillators or any high impedance rf circuit.
Thank you for carrying this product. In a day and age where this is a dying art, it is always refreshing to visit your web site and find exactly the part I need to complete my projects.
