When does a tube become a Premium Selected tube?

Power tubes
All power tubes labeled Premium Selected have passed the following tests:
-      Plate Current (PC) and Amplification (TC)
-      Low Noise Test
-      Microphonic Test
-      Sonic Tests
-      Shock Tests
-      Listening Tests
-      Shorts & Leakage Tests
 
Premium RT-Matching of Power Tubes
Our Premium Matching is an exact matching of power tubes with identical Plate Current (PC) and Transconductance (TC).
 
TAD Premium Selected tubes are guaranteed for a period of 6 months (according to terms of warranties)
for the quality criteria mentioned above.
Preamp tubes
All preamp tubes labeled Premium Selected have passed the following tests:
-      Low Noise Test
-      Microphonic Test
-      Gain Test
-      Sonic Tests
-      Shock Tests
-      Listening Tests
-      Balanced Output Test
 
 
Premium Selected
We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.
For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection
 
HIGHGRADE SELECTION
But only those tubes which pass these tests best are labeled Highgrades.Typically this is approx. 3-10% from a production batch that qualifies for the HIGHGRADE rating from TAD.
Due to the very high selection requirements, this article is temporarily only available to a limited extent! Please note our shop-information on availability.
 
Matching and Selecting Options for Preamp Tubes
Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.
This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.
 
TAD Premium Selected/Highgrade tubes are guaranteed for a period of 6 months (according to terms of warranties)
for the quality criteria mentioned above.
