Up for sale, two (2) used US General Electric 5751 tubes. Identical construction with black plates, triple micas, extra support rods and D getters. Test numbers match fairly close. The only thing is almost all the white print has come off. 5751's often test higher than 12AX7s, which may be why they work well and sound great in 12AX7 applications. These were tested in a phono preamp also, with no unwanted noises.
Tested high on Hickok 539C tester: (850 minimum)
Tube #1: 1450 gm, 1.2 mA current.
1500 gm, 1.3 mA.
Tube #2: 1600 gm, 1.3 mA.
1650 gm, 1.5 mA.
Buyer will receive 2 tubes, as shown. Will be well-packed and shipped within US, free of charge, by US Postal. Charge for overseas mail. Asking US$69.
