    • CIRCUIT: As on 11-4 circuit but with the following alterations:- (Note: Enclosed diagram in lower right hand corner of sheet does not apply).
    1. Tone control (0.5 Megohm Potentiometer) replaced by 2 position, 0.02 μF 600v. condenser (C95) and 0.5 Megohm ½ watt resistor (R117). Disconnect lead from centre lug of potentiometer, and wire it to stationary contact of switch. Earth moving arm of switch. Replace potentiometer with fixed resistor.
    2. Speaker 70-1 was replaced by speaker 70-8.
    3. H.T. choke (28-3) to replace field of 70-1 speaker.
    4. 6J8G valve replaced by EK32 converter.
    5. Remove lead connecting 6J8G screen to 6G8G, wire 0.05 μF 200v. (C21B) from EK32 screen (pin No. 4) to ground. Wiore 0.05 Megohm (R14) from 6G8G screen to B+, replace 0.03 Megohm (R136) with 0.015 Megohm (R140).
    6. Power transformer 18-27 changed to 18-32.
    7. 5Y3G valve replaced by 6X5GT rectifier, (6X5GT heater connected to 6.3v winding on transformer).
