Default Re: 'Beau Decca 131 projection receiver 1950'

The pictures show the final local oscillator coil for channel 1. The switch off spot showing the dark areas of the poisoned cathode giving low tube emission.
The original oscillator coil and the complicated sync separator necessary for the excellent interlace required by a high magnification projection system.

Just the tube to replace and sorting out the lack of sound. Regards, John.
