I am looking to reduce my inventory of these highly-regarded 12AX7 substitutes. These are 1950s military-specification tubes designed for low noise and long life.
All tubes test excellent. Most of them have partial logos. Better logos are available for a slightly higher price.
I can send test results and pictures upon request. Just let me know what and how many.
GE 5751 3 Mica Black Plates from middle to late 1950s are $70 per pair.
GE 5751 3 Mica Black Plates with Silver Clips from 1952 - 1954 are $100 per pair.
RCA 5751 3 Mica Black Plates from middle to late 1950s are $85 per pair.
Let me know if you have any questions. Thanks for looking.
