The Ekco is a 7" CRT vision only TV receiver designed as a low cost entry model. The audio from the demodulator can be connected to the pick-up terminals of a radio receiver.
Earlier this year when the set was unattended the timebase mains transformer burnt out filling the room with black smoke. Mike Barker rewound the transformer to exactly the same specification and appearance of the original part.
Failure of the transformer can be attributed to the 8mfd reservoir capacitor having gone short circuit. The Mazda UU5 HT rectifier was also destroyed.
Work done so far is clean up the mess on the chassis and fit a replacement reservoir capacitor. The mains transformer will be fitted tomorrow.
There's evidence of sloppy 1990s repair work has been done to this set. Again, such work doesn't look right in a rare TV set made in 1938.
For a set designed to sell for a reasonable price it could be said it is a rather over-engineered receiver, for example three mains transformers!
