8 transistor superhet with RF stage and push-pull audio output.
The construction was typical of valve design with a chassis and the transistors mounted in sockets.
It used eight transistors, four of European manufacture in the audio section (OC71 and OC72 types) and four American RCA transistors in the higher frequency stages (2N219 and 2N247). These RCA transistors were early “diffused field” types, developed to minimize semiconductor junction capacitance and make them suitable for RF applications. They also had a fourth connection lead, an internal screen to reduce external noise.
Rola 4x6F elliptical speaker.
