Recommended Posts

12ax7 GE,RCA and Sylvania NOS tubes $20 each. Some tubes have great print others do not. All tubes have been tested on a B&K 707 Dynamic Mutual Conductance Tester. They have been screened for Sound,Gas,Shorts and Microphonics. Some tubes may be slightly used but all test at NOS levels.


I have other 12ax7's that test slightly under NOS levels for $15 each (GE,RCA,Sylvania)


Also have Power,Pre and Rectifier tubes available.
