A bit odd that young David, 'cause I remember the DRR2 as a valve coil. I've got one which I managed to snaffle at a sensible price from someone on the other Forum. It came with circuits which I think include, one using the Feranti chip which was popular in the '70s I think. I'll try and dig it out.
I've got more circuits using multiple valves, but they all valves, not transistors.
One of these days I'll have a play.
