Default Ferguson 357BT

After it residing in damp sheds and garages for over 50 years, I managed to finally make this thing work.

Sans case.

Sans wavechange switch.

Sans battery holder.

Sans loudspeaker.

Complete with a wire from the ferrite aerial floating about unconnected.

Even when the wire was soldered back on the tab of the tuning capacitor whence it would appear to have come the thing still wouldn't work.

After much effort it turned out that the tracking was off, the beat frequency being 800kHz rather than the more expected 470kHz.

Turned out that one section of the winding on the ferrite slab was pushed too far towards the other winding.

Simply moving them further apart did the job: MW stations finally received successfully.

Magic.

It only took a month.

Naturally enough the circuit diagram for said set resides in the one red book I don't have, but the interweb eventually came up trumps.
