For info/Decca coil mods.
54 uH coil using powdered iron core (T200 - TYPE)
resistance 0.4 ohms using 18 mm enamelled
copper wire, single layer.
54 uH coil using original decca paxolin former and
original litz wire 0.5 ohms.
The iron core has a slight advantage plus only a
fraction of the physical size.
Using a ferrite core, would require less turns to
achieve the 54 uH value, heavier wire could be used with resistance advantages.
The cores that I used are Genalex G1T
26R817 original Decca, out of the phase loop transformer assembly unit, about
the same size as a T200.
