Summary

Harry Lythall presents a remake of Denco Coil on his website; http://sm0vpo.altervista.org/3d/denco_sub_01.htm
On his website is all necessary for the calculation and winding of these coils

Quote: Harry Lythall

"Denco produced RF antenna, oscillator and IF coils for superheterodyne receivers, covering 150kHz through to 31MHz. These coils formed the basis of many school and college training programs, in design, assembly and alignment of superhet receivers. They had ranges for valves (tubes) and transistors. The coils came in an aluminium tin, with a screw-top, that also doubled up as a screening container for the coils in use."

Because I thought it is an interesting project I made it more like the original (Standard Noval Socket B9A) and two heights.
