Matched pair of Amperex Bugle Boy 12AX7 tubes. Matching codes of mC1 B6I. I beleive these are from 1956 and produced in the Mullard Blackburn factory. These are square getters with bent dual strip ends. The lettering is excellent on both tubes. These are fully functional and used in a previously owned preamp, but I do not have a tube tester to verify measurements, unfortunately. I will guarantee they will not be DOA and are fully functional, but can't guarantee lifespan.
I have more pictures if you want them. Just let me know what you would like to see. I'll pick up the shipping and PP fees. $225 for the pair. Offers considered.
