P-C70-RF Coil - Miniature adjustable coil, 70, R.F. stage
Coil is similar to Miller number 70-RF. Coil is similar to Miller number 70-RF R.F. stage 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 R.F. coils have high impedance primaries and wire wound secondaries for use with any variable condenser having a maximum capacity between 250 and 450 mmf. These coils are for use in all common padded and unpadded oscillator circuits.
