TAD 6550A-STR PREMIUM Selected.
 
NEW Version: since Sept. 2010 the TAD 6550A-STR is made with a reinforced and very pure anode material. Combined with the advanced TAD burn-in process, it has achieved unprecedented consistency in performance, surpassing even the 6550C Svetlana -C- in critical applications such as the Ampeg SVT.  (Only suitable without tube retainer!)
 
 The TAD 6550A-STR is a loving remake of the classic GE 6550A tube with a heavy, straight glass bulb, classic build with triple getter, metal base and excellent linearity.
It is characterized by an extremely balanced, natural reproduction of all frequencies and helps with an incredibly powerful bass range and fine shine in the relaxed playing heights to a very lively sound.
The TAD 6550A-STR meets or exceeds the specifications of the classic 6550A tubes and can be used in any 6550 application with excellent performance.
 
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.
