IIRC, OC82 was an output transistor in an ally can. OC71 was the common
general purpose type.


And the audio line-up in a good transistor radio of that era was an OC71
feeding an OC81D driver feeding a pair of OC81s in push-pull
(transformer coupled in and out). For the RF side you had an OC44
self-oscillating mixer and two unilateralised OC45 IF stages.

Nostalgia...


And the AF115 for the VHF or was it 114 ???

And the AF139 in yer TV amp

Them were the days...
