Remake of the Classical GE6550A - TAD 6550A-STR PREMIUM Selected
 
NEW VERSION: Since Sept. 2010, the TAD 6550A-STR has been manufactured with a stronger and exceptionally pure anode material combination. In conjunction with the extended TAD burn-in and formating process, the 6550A-STR reaches an outstanding consistency and stability and outperformes even the 6550C -C-.
This makes the 6550A-STR withstand even the most critical application like e.g. the Ampeg SVT.
(Fits only without the tube retainer!)
 
The TAD 6550A-STR is a true remake of the vintage GE 6550A with a heavy, straight glass envelope, polished metal base and the authentic triple getter construction. A balanced tube, known for its incredible bottom end and rich mids. Smooth, liquid bass, natural sounding tone and a wide open character make this tube extremely popular for bass guitar amps and High End Hi-Fi applications.
The ratings of the TAD 6550C-STR meet or exceed those of the classic 6550A tubes. It performs superbly in any application asking for 6550.

TAD recommended this 6550A-STR for the AMPEG SVTs. My SVT was "eating" 6550WEs within a few months. The TAD 6550A does work now since over a year with great power and delivers the best tone I ever achieved from my SVT.

Thanks to TAD for that excellent 6550A-STR and the great support finding the right tubes.
