  • Notes
  • The Dynatron Commander chassis shown on the Keates-Hacker stand is virtually three receivers in one. A straight circuit is provided for local station reception, a "normal" superheterodyne with a redesigned variable selectivity system giving true band pass characteristics even at 4 kc/s bandwidth is employed for general reception, and on short waves a double superhet circuit with two RF stages is brought into operation

    There are twenty five valves in the circuit, four of which are triodes working in push-pull to give an undistorted output of 20 watts.

    Refinements include noise suppression circuits, a manually operated adjustable whistle filter, and a cathode ray indicator for grid current in the output valves. The chassis is built on a machined aluminium casting and costs £165.

    This chassis is used in some Keates-Hacker receivers.
