Description

This lot consists of four 2A3 tubes. Two are made by RCA, another by GE, and the last by National Union. All are in good physical shape with no rattles or loose parts. Transconductance (Gm) and plate current (iP) test results are well above the minimum and at/near NOS spec in several instances. Please review the pictures to see exact test results. TESTING: The tube(s) in this sale have been tested on an Amplitrex AT-1000 tube tester (fixed-bias mode), which is a laboratory-grade tester capable of supplying the user with precision measurements. It tests for heater-cathode leakage, gas, mutual conductance, and plate current. Please note that no tube testers are identical and my test results will likely differ slightly from yours. RETURNS: I will gladly take your tube(s) back for a full refund if you're unhappy for any reason. Yes, it's that simple! Please note that I reserve the right to issue partial refunds if tubes are missing, damaged, or without original boxes (when applicable).
