Managed to salvage a pair of B9A tubes from an old Rogers Console.
Rogers 12AX7 - I65 & r3L4 code which is Phillips Ontario.
Phillips MiniWatt ECC85 - tU3 & a "Right Angle Triangle symbol"4C3 code which is Philips Heerlen.
(Filament current possibly a little to high on the ECC85.)
Now I can play, I have a salvaged B9A socket and I'll make up some plugs for the LD's B7G sockets in the next few days.
