  • Notes

  • This Exelrad 5GX Kit Set is a considerably revised version of the " Dual-wave Comet," which proved so popular with constructors. It was decided to maintain the series of glass valves for this model, primarily on considerations of initial cost, since metal valves are higher in price than the glass types. Also, in order to obtain good performance with a minimum number of valves, the familiar 6B7 dual-purpose detector and amplifier is used, and this has not, as yet, been reproduced in metal. The tuning ranges are 550 to 1500 kilocycles per second, and approximately 6 to 16 megacycles per second. 

    Kitset Prices:

    With valves and speaker........£15 / - 

    Without valves and speaker...£10 / 10

    With valves less speaker........£12 / 5
