Hello Alan I had that in the back of my mind, quite expensive in their day, built a couple of practice amps with them, one ended up in Vancouver! Might have been a PW design. I built them circa 1964/5 and they were a pretty new valve then so must have been released around that time. Poss 10 pin jobs.
Line O/P valve PL509/519 were there any after that I wonder.
