Data on Vintage Denco coils used by the Radio Constructor.

From the 1950's to the 1980's Denco coils were used by large numbers of radio constructors,kit manufacturers and others. Now no longer being manufactured they are mainly found at vintage/ham radio meetings and on EBay. These are some of the actual data sheets issued by the manufacturer.

Coil Ranges. The ranges were designated by a different number from 1 to 5. And as will be seen the range number was applied to all coils from the Aerial (Blue Coil) to the Yellow,Green,Red and White coils. The circuits show which colour was ment to go in which position. There were of course differences between the valve coils and ones for transistor circuits. But all is explained in the text.

The coils most in demand today are the Green shortwave coils for shortwave TRF receivers.
Most of the Denco coils appear for sale on Ebay throughout the year so if you need coils it is worth putting a standing search on Ebay.
Other pages on this site giving further information on coils are here Constructor Coil Information.
