Mullard 10M Series 12AX7 ECC83 Red Tip Gold Pin Tube, NOS Testing
The red tip indicates that this tube was factory selected for low noise.
It has gold pins, gray ladder plates, and a halo getter. It was manufactured in England in the early 1970's.
This was tested on my Dan Nelson calibrated TV-7/B. It has been tested for shorts, gas, and transconductance. The tube tests with a reading of 50/52. Minimum is 32.
I will ship international.
