Product information "6L6GCM-STR REDBASE TAD PREMIUM Selected"
Our answer to the challange to build the best 6L6 type tube ever manufactured!
brandnew in 2021
The TAD 6L6GCM-STR REDBASE is our latest 6L6GC designed and built  to claim to be the best 6L6 type tube ever manufactured.
A damn high claim, but we are sure that we have achieved exactly that.
In terms of sound, the TAD 6L6GCM-STR REDBASE produces the powerful but always defined bass response known from the legendary american built NOS RCA 6L6GC, with clear, unobtrusive and yet transparent highs. In every setting, the TAD 6L6GCM-STR REDBASE responds directly and with noticeable dynamics, from buttery soft and warm to powerful and brutal without losing any details or depth.
This makes the TAD 6L6GCM-STR an effective upgrade for every amplifier using 6L6GC or 5881 tubes; also repalces any EL37, CV586, VT115A, 6L6GA, 6L6GB, 6L6WGB, 6L6WGC, STR-440, STR-454, 6p3p, 6p3s, 6p3s-e etc.
The TAD 6L6GCM-STR REDBASE combines the structural advantages of the robust American Philips / Sylvania 6L6GC, also known as MESA 6L6GC-STR415, and the sound quality of the legendary RCA 6L6GC tubes.
Silky highs, defined, deep bass and lots of headroom recommend the TAD 6L6GCM-STR REDBASE for lively clean sounds as well as a powerful broadband power amplifier for multi-channel amps.
The new TAD Redbase series combines the latest manufacturing technologies with traditional design and flawless quality. The TAD Redbase series is exclusivly built on a TAD production line that has been optimized especially for the TAD Redbase series. At TAD in Germany, the tubes of the STR series receive a special, additional burn-in treatment and formatting process in preparation for the TAD Premium-Matching, which optimizes the quality of the cathode emission and opens up an exceptionally detailed sound structure.
The Classic 6L6 Sound - Excellent Tone and Maximum Lifetime!

Customer evaluation for "6L6GCM-STR REDBASE TAD PREMIUM Selected"

One great tube!

This is by far, one of the best, new production tubes on the market today. I have tried many tubes and can with certainty that this almost rivals the Sylvania 6l6GC double halo getter...almost, but at a quarter of the price! Time will tell if these hold up over time but I am enjoying the ride so far!

6L6GCM-STR REDBASE TAD PREMIUM Selected is the best 6L6 tube.

I have a very small combo self made, with Chinese tubes, one 6L6 and two ECC83, 8" Jensen and solid wood case open backside.
First upgrade I have changed the two ECC83 with TAD7025 WA, obtaining a sweeter tone and more rounded overdrive.
Then I have decided to change also the 6L6 with 6L6GCM redbase selected, that I have requested with low transconductance for the better headroom, after a suggestion of TAD's service.
Put 6L6GCM-STR REDBASE TAD PREMIUM Selected in my amp and this is the fact:
- incredible and wonderful sound, there is a dramatic difference with the previous Chinese tube 6L6GC,
- more defined sound, more headroom, more presence, more harmonics, expecially in triode configuration
- more sound pressure and headroom in tetrode configuration
Many compliments because surely your product is one of the best and what you declare is really what a client can obtain: TAD 6L6GCM-STR is an effective upgrade for every amplifier using 6L6GC, it's true, also for a small open combo with 5watt.
