If I manage to obtain supplies of these transistors maybe I'll have the odd one to spare. They seem cheap to buy.
I've been racking my brains on the basic transistor theory. After some observation it seems to me the P423 transistors in the schematic are common emitter. I'm not at all used to non valve circuits but my ARRL book seems to show these as PNP with grounded emitter?
