These small roller inductors are used in the multiplier tank, driver tank,
and antenna output circuits.
The roller inductor is 1.25" diameter - the slider contact arms are worn, do not work well, slip off the coil, and need replacing.
If you have any parts like this please send me e-mail with info. Thanks, Nick K4NYW
|The contact arms are grooved to (theoretically) ride along
the coil. The contact arms are spring loaded to press against the coil.
As the coil rotates the contact arms pull the slider bearing assembly sideways along the slider contact bar.
Some coils have one contact assembly, others have two.
