The BFO/DF module can then be re-fitted along with the valve sockets and tall tubular
capacitors in the IF/AF section … followed by the heater (LT+) wiring, in blue. The
photograph above right shows the chassis wiring complete from the RF amplifier up
to the audio stage.
The wiring around the Master Switch can be very daunting … perhaps more so than the
Coil-Box. Whereas the coil-box can be re-wired off the main chassis, the Master Switch
must be wired more or less ‘in situ’. At this point L23, C56, the chassis mounted
block capacitor and the remaining front-panel switches are fitted and wired up.
