 Q: What criteria does a power tube need to meet to  qualify  as Premium Selected ?
 
 A: We only name those tubes  Premium Selected  that passed the following tests:
 
 - Quiescent current (PC) and slope (TC)
 
 - Noise test
 
 - Microphone test
 
 - Acoustic tests
 
 - Shock test
 
 - Listening tests
 
 - Short circuit and fault current
 
  
 
 Matching power tubes
 
 In our  Premium RT matching  , our tubes are not only matched after the quiescent current (PC), but also the slope (TC) is taken into account. Both data as well as the batch and sorting numbers are applied to both the packaging and the tube.
 
  
 
 TAD Premium Select tubes include a 6-month warranty (under warranty conditions) for compliance with the above quality criteria.
