Well I accumulated these RCA's with no silk screens and this cleans off the 12AX7 shelf for now. Here are (8) RCA made in USA 12AX7A (2 are 7025's) twin triode's that I have tested on my Heathkit TT-1 Mutual Conductance tester. The minimum for a good 12AX7 tube on this tester is 1040. They test: 1600/1300, 1400/1400, 1500/1500, 1750/1250, 1800/1700, 1100/1300 and the 7025's 1800/1900 & 1500/1400. I guarantee these tubes are useable and will combine shipping with your other winning bids.
