1950 12" Defiant TV set.

[Geordie McBoyne]

The RF pentodes are the Mazda 6F1, this B8A base valve later morphed into the 30F5. Main difference between the 6F13 and 6F1 is that the latter has two cathode connections, pins 5 and 7.
The set has an HT smoothing choke so a PM loudspeaker can be fitted.
The underside of the chassis is in excellent condition.
