Tube Amp Doctor 6550A-STR Power Tube

This TAD 6550A-STR is being 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. The TAD 6550A-STR is a faithful 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 their incredible bottom end and rich mids. Smooth, liquid bass, natural sounding voices and openness made this tube amazingly popular for bass guitar amps and High End HiFi applications. The ratings of the TAD 6550C-STR meet or exceed those of the classic 6550A tubes and can be used with great performance in any application asking for 6550.
