Pair of rare, strong, and well-matched 1957 Mullard
12AX7/ECC83 tubes with long plates, square getters, and mC1 production codes
(B7K and B7F). Purchased as a matched
pair from Brent Jesse (audiotubes.com) in 2008, used less than 100 hours, sent
to Tyler at TC Tubes (tctubes.com) in 2015 for testing with Amplitrex AT 1000, and
then not used. See photo of boxes for
test results, where percentages are % of expected Gm and iP values of new tubes. Both tubes have low noise and low gas (0 and
0.1 for tube in top box, marked as “The Fisher”, and 0.1 and 0.1 for tube in
lower box). See review of these fantastic tubes at audiotubes.com, where a matched pair now sells for $525.00.
Condition listed as Very Good based on test results.
Free shipping for continental USA.
