Description: This is a set of three genuine NOS (new old stock) RCA 5691 tubes! All share identical 1976 date codes of "76-13" and feature the classic red base, black plates, a third mica level, and support rods. All test beautifully above NOS spec and are tightly matched (see pictures for 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).
