Where can I find good-sounding and qualitatively high-quality tubes for Trafomatic tube devices?

With Trafomatic Audio, tube selection depends strongly on the respective device, because the brand ranges from classic 300B SET concepts to powerful KT120 and 6550 / KT88 amplifiers. This applies, for example, to Experience Two MK II and Evolution Two with 300B, to the EOS with KT120, and to the Evolution Elegance with 6550 / KT88. Especially with Trafomatic, the tubes are not only part of the configuration, but also significantly shape the character of the amplifier. Anyone who wants to preserve such a device or equip it correctly again therefore needs the right tube for the exact model. Many suitable types for Trafomatic are available from BTB in carefully selected quality.
