Let us not forget that he made a class D amplifier in the early to mid 60's and then there was the Sinclair IC12, an early "gain clone" type IC, at a guess probably made for him by Plessey
Jez, my memory is very hazy on this, but as I put in my previous post, I thought the tiny 'Butterfly' amp I had was a Sinclair. There was also an even smaller on the size of a matchbox, I think. This would have been late 70s/early 80s though I didn't buy it new. Maybe I'm wrong and it wasn't a Sinclair but what I remember seems to fit, as it was shoddily made and didn't last. Maybe that was of the gain clone or class D you mention.
