Tube Amp Doctor (TAD) Vacuum Tubes

TAD 6550A-STR PREMIUM Selected. NEW VERSION: since Sept. 2010 the 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.(Fits only without the tube retainer!) 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

This all new TAD 6V6GT-STR combines the exceptionally sweet voiced NOS 6V6GT like the RCA or GE 6V6GTY updated to withstand higher operating voltages due to raised AC supply. At the same time this TAD 6V6GT-STR produces surprisingly tight bass which you wouldn't expect except with the most select real NOS 6V6GTs.
