NEW VERSION : Since September 2010, the TAD 6550A-STR has been made with a combination of tougher anode materials of exceptional purity. Thanks to the extended TAD burn-in and forming process, the 6550A-STR achieves remarkable consistency and stability, even surpassing the 6550C.
It can therefore withstand the most demanding applications, such as the Ampeg SVT.

The TAD 6550A-STR is a genuine reissue of the vintage GE 6550A, with a thick, straight glass envelope, a polished metal base and authentic triple-getter construction. A balanced tube, renowned for its exceptional bass and rich mids. Fluid, precise bass, a natural tone and great openness make this tube an extremely popular choice for bass amplifiers and high-end hi-fi applications.
The TAD 6550C-STR matches, and even surpasses, the performance of the classic 6550A tube. It excels in all applications requiring a 6550 tube.
