I have 2 new in the box same dated super quiet 1961 medical red tip mullards 12ax7a tubes labeled for Westinghouse and sold to Honeywell medical systems.These tubes are closely matched at 1400-1400 and 1350-1400 where 800 is minimum good and new tubes test 1200 to1250 on my hickok.

All tubes is checked for shorts gas grid leakage and life and then put in a headphone amp to check for noise.
