-
Table projection television receiver, giving picutre size of 16 x 12-in.
Receiver is permeability-tuned over the five channels of Band I. The front end of the receiver is detachable so that it can be replaced by a Band I/Band III tuner unit. Beam current a.g.c. is applied to the final vision i.f. amplifier and this ensures maximum peak white defocusing and enables the set to be operated at a high average brightness level.
