Review DIA Three Rotary Inductor Coil Size Inch Turns 15.5 Uh Need Repair
Could use exit cleaning, Alignment is messed up. Overall Size: 6 inches from end to end, 5 high and 3 wide. Pluses: priced cheap, A project I am choosing not to do myself this time, enough springs for two units, Ceramic parts have any cracks or chips, Rollers look be good. This listing is for THREE B W rotary inductor, all of which need some TLC.

Issues: one roller wheel shaft has corrosion, 2 tension springs are missing each unit needs two, you might be able to make two more. NOTE: Buyer pays return shipping.
