High Performance Audio Beam Power Tetrode.  The new TAD KT88-STR REDBASE is built in the style of the early British MOV KT88 with the big and heavy glass envelope and beautifully polished metal base.

The REDBASE features a gold control grid for outstanding low-noise performance and reliable stability.

A breath-takingly big and precise tone and great appearance make the new TAD KT88-STR REDBASE the best choice for both, high-end audio applications and powerful bass guitar amps, providing a natural and three-dimensional tone with a very musical response, with great sound and finest details in mids and top-end; a linear and harmonious overall response with a very organic tone, make the TAD KT88-STR REDBASE our favourite tube in the KT88 and 6550A class.
