Description: I have many audio tubes to sell, and simply don't have the time to list each tube individually. So, I'm selling them in this format. This saves me a little time and gives you a great tube at an unbeatable price. Please read below to understand the terms of sale: These tubes are being sold individually. Each tube is boxed with the test results. All of these tubes are genuine Amperex tubes from the Heerlen factory. Most are short plate like i61 and i63. All have the "delta" symbol etched in the glass near the date code. Date codes vary, as do cosmetics. Some have excellent printing, some labeled for other brands, and others have almost no printing left.Transconductance (Gm) NOS spec on the Amplitrex is 1600, minimum is 1200. These all tested at (or above) 1300, with many at 1600 or slightly higher!I will ship the "best" tubes first.You're more than welcome to buy multiple tubes and I'll do my best to get you a matched pair. However, I will be matching simply by test results and not date codes, type (i61, etc), or cosmetics. You're more than welcome to return the tubes for a full refund (at my expense) if you're unhappy in any way! 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.
