In the Air Ministry document there is shown a 0.5uF (C16) decoupler between pin 4 of the BFO box and chassis. This is missing in the Radio Constructors drawing and is assumed to be a drawing error. 16/12/03 |

The 75pf trimmer on the anode of the BFO triode goes to earth not the cathode of the valve. The revision 2 cct shows this. 21/12/03 |

There is a 1600pf (2 x 800pf) connected between the anode and cathode of the BFO triode.21/12/03 |
