That's it! Cheers James.

I'm tempted to try re-creating some of the designs; I have foind memories of playing around with a Reflexed receiver built from that book, which worked quite well using an OC44 as the RF transistor. I remember though burning my fingers on an OC81 used as a single-ended Class-A audio output transistor when its simplistic bias-network let it go into thermal-runaway.

ah, happy memories!
