The new TAD 6V6GT-STR REDBASE tubes where part of the planed expansion of the series for 2022, finally now available from stock. As Tube Amp Doctor explains, these beam-power tetrode vacuum tubes shine with the typical NOS "sweet top end" and a strikingly dense and complex midrange, but with the reliability of brand new tubes.
"This special and organic midrange character produces a tonal liveliness that otherwise only NOS 6V6s are able to achieve and which remains unparalleled. When pushed into saturation, there are no harsh upper mids, which is frequently the case with other 6V6s," TAD explains. Other reasons why guitar amplifier manufacturers are embracing the new REDBASE heavy-duty 6V6 tubes are related with its "sweet, full-bodied tone with silky highs, superb responsiveness, and outstanding dynamics," they add.
A completely new development, the TAD REDBASE series is built on an optimized production line - exclusively for TAD and only for this series. It combines the latest manufacturing techniques with traditional design. To ensure the quality, all TAD 6V6GT-STR REDBASE tubes are individually tested and approved, selected and premium matched. In preparation for the unparalleled TAD-premium matching, the TAD REDBASE series tubes receive a special, additional burn-in and formatting process in Germany, optimizing the quality of the cathode emission and achieving an exceptionally detailed sound structure.
Primarily serving the guitar amplification and effects market, which still involves the highest volumes in audio applications for tubes, Tube Amp Doctor has been around since 1993. With a continuously growing reputation and an expanding product line of top-quality tube amp equipment and parts, TAD has become Europe’s leading tube supplier, sourcing its tubes from one of the only remaining manufacturers in China.
