Howes Roller-Inductor This is the roller inductor that I use on my CR-5 Crystal Radio sets. Those that enjoy there hobby building crystal sets and experimenting may find this item of interest. It consist of 105 turns of #24 copper wire around a 1-1/2" coil form that is 3-3/8" long. I think the picture shows the rest of the story. I can't give you any exact inductance values, but seems to be ideal for crystal sets or possibly tuners. Thanks for looking.
