Mullard 12AU7A (closely matched pair) Short Grey Plate-Blackburn-Maxi 2 Tested

Description: This is a closely matched pair (quantity of 2) of Mullard 12AU7A's, GF2's made in the Blackburn plant and that have a short grey plate with a round halo getter. They have the 1022 EIA code for Mullard visible on them and the signature hole betwen the staples on the plates. Hammond branded that are organ pulls and retain almost all of the screen printing on the tube. Test results were done on a MaxiPreamp2 tester. I tested for microphonics in an amp as well as the Maxi tester for noise and they both were near -86db (the lower the number the better and -86db is the lowest I have personally seen for any preamp tube). Mullard 12AU7A #1: Gm 1470/1454 Mu 17.4/16.9Mullard 12AU7A #2: Gm 1506/1536 Mu 16.0/16.8 I ship by next business day (most times same day if payment is received by 12PM CST) to CONUS.
