Details:

The best way is to calculate the GM - and check data sheet for each tube a nos should typically measure between average maximum micrometers GM. 90 % of our tubes are Tv7 tested, tv7 is Calibrated and go to tester. These tubes have been tested - and are considered NOS ; they meet or exceed the published data set for GM. Noise and Micro phonics are often buzzwords for other issues.

Tubes test NOS. Shorts/ leaks. PLEASE message me BEFORE you open a return. Send me a message.

I DO NOT OFFER A TUBE ROLLING SERVICE, vintage audio tubes typically require a burn in period, that's where the tube sounds best. There isn't a specific indicator or result data set anywhere that universally designates vacuum tube as new old stock when using tester nor for what test is given. The tv7 tester has been around a long time and is trusted for military, who had high standards reliable tubes that would not fail in critical conditions. Tube tester NOISE TEST.

I will bend over backwards to make sure that you are a happy customer, prior and after purchase. In properly designed circuits objectionable tube noise is seldom found. Always check the data sheet of tube you plan to use. If you don't like the sound of a tube, so long as it is still in same condition arrived message me.

Test Results are ALWAYS available upon request if not photographed. Tv7 tested TUBES. There is a small percentage of tubes that have problem with noise but far less than most people think. Military standards were tubes needed to meet 60/65% which they established as minimum value.

This is a very marginal test, only for special checking. This test needs sound amplification; hearing / listening to noise with headphones would indicate a real disaster inside tube THE shorts WOULD already BE evidence OF THIS. Please see my notes on noise tests below.

It can be wiped off and destroyed VERY easily. Sound quality is tremendously SUBJECTIVE. Hence, most people advertising tubes as tested for Noise or Micro phonics are probably NOT testing them in any meaningful way FOR YOU OR YOUR AMP. NOS tubes fall within the Gm characteristic range of an average tube, as published in RCA RECEIVING TUBE MANUAL, which states Individual tubes, like any manufactured product, may have characteristics that above or below values given.

Some testers do have noise test jacks that connect to either headphones or the antenna/ground terminals of an AM radio. Tubes do not give the same reading across testers - even model tester will a different sometimes. Looking for something else and want to save on shipping. There is nothing wrong with performing that noise test however.

All our tubes have been tested for.
