RCA Tube Value?

[jaymanaa]

Any ideas on the value of a matched pair of NOS RCA (made in Great Britain) 6CA7's (EL34). They don't appear to be Mullard (no hole in the guide pin). Who else made tubes for RCA in G.B.? Double getters FWTW. Thanks, Jay

BTW I'm asking cause I bought a pair in a pissing match on E-Pay and wandering if I'm an idiot' :dammit:
