I've been going through some old 12ax7s and trying to see what I actually have. Can anyone give me some info if these are mullards or what they are . . .?
1.) Rogers 12ax7a
Writing is blurred and cannot make out where it was made.
Has the code I (7?) 65 r4BI on the side.
2.) Ge 12AX7A/7025
Made in Japan
Code = A5 JX
3.) Marconi 12AX7A
Made in Japan
Code = PN
Any help would be great. I was thinking of buying some Mullard 12ax7s and thought I should first see what I already have.
