Also included in the instructions is a 2 valve amplifier kit which was availiable from HAC. The pictures below show a chassis made for me by Nigel Claricoats which also has a hole cut out for an octal valve holder. Hence different models of the HAC receivers can be built.
The set has proved lively after dark. And there is no problem picking up Europe/Africa and the Americas (in Kent).
When using the receiver as a tuner for an amplifier the headphones were replaced by a 4k ohm resistor and a 0.1uf capacitor connected to the anode of the 1T4 valve. There are also two pictures of the chassis fitted with a jack socket and driving headphones from S G Brown Type F and a pair of Ericsson of Batley Yorkshire.Both types have 4k ohm coils fitted (ie 2 x 2k).
It has been found possible to receive stations with an HT voltage of less than 35 volts.
See also the HAC DX page for another model K built by John (G4JGG) HAC DX.
