Manufactured
in an exclusive production facility, the TAD REDBASE
® series is not only the first choice for musicians
and hi-fi connoisseurs, but also for leading amp manufacturers.
In 2020, Tube Amp Doctor invested in a new cooperation
with a small manufacturer in China to produce a completely
newly developed tube line: the TAD REDBASE ®.
Through the combination of tradition
and innovation, through investments in production
facilities as well as their expansion and modernization,
we have succeeded in building premium tubes with the
TAD REDBASE ®, both in terms of quality and sound.
TAD REDBASE® tubes undergo the toughest tests
in the industry directly at TAD in Germany. Since
November 2024, we have introduced the Deep-Drive &
Soak test, which checks all TAD REDBASE output tubes
before matching for power performance consistency
under continuous full load.

EL34-STR Redbase premium selected matched QUAD
The new TAD EL34-STR REDBASE™ developed completely
from scratch! The results are phenomenal. In the tradition
of the legendary Telefunken EL34, the TAD EL34-STR REDBASE™
provides a gorgeous, dynamic and amazingly open in-yer-face
tone with just the right amount of angriness. Expect
a clear, harmonic and open top end, a lovely spot-on
midrange, with vocal low-mids and a great bass response
as you would expect it from a TAD EL34.
Extra rugged glass envelope, golden control grid wire,
two especially large cooling grids and special high-precision
construction with smallest tolerances guarantee for
maximum stability and reliability..
The TAD EL34-STR REDBASE™ differs from other EL34
tubes in particular also by the extreme quality control
in the production and the special formatting of the
tubes by TAD in Germany before the actual matching.
The TAD EL34-STR REDBASE™ can be used for any
EL-34 and also instead of 6CA7 and KT77
It is therefore ideal for guitar amplifiers as well
as for HiFi equipmen

KT88-STR Redbase premium selected matched QUAD
High Performance Audio Beam Power Tetrode
Our 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 threedimensional tone with pleasingly
full warmth and fine, subtle highs.
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.
