Preferred Series 6L6GC
This 6L6 tube is a new version of the popular TAD 6L6GC-STR you might already know. Once exclusive only to TAD (Tube Amp Doctor) we contracted the Shuguang factory in China to produce a massive lot of these tubes to our specs. We think this is a better tube and at a better price.
The Preferred Series 6L6GC construction features:
- A black plate like the premium NOS RCA 6L6GC tubes from the 1960's
- Double halo-style getters
- Gold grid wires
- The filament used is low-noise
- The bottle is made with a heavy gauge glass
- And finally the blue color base is a nice touch too!
This 6L6 tube is versatile and will sound great in many amplifiers, for many styles of music. Anything from blues to jazz to metal. It is well balanced from top to bottom. The highs are smooth, clear and clean. The low end well detailed and articulate even when pushed hard. We think this is the best alternative to the famous Philips/Sylvania STR-387 6L6GC.
From our review: "This tube has a sound that I would characterize as smooth and warm. The high end is articulate but not sharp or brittle. Bass response is bigger than most but not boomy, so you still get good note definition. The midrange is very nice and thick without any tendency to sound nasal."
The Preferred Series 6L6GC tubes carry a 6 month extended warranty.

Ratings & Reviews

These are the best tubes I've heard in my '69 Super Reverb since the original RCAs went bad! Excellent clear, sparkly tone and they overdrive so smooth. They have a little less bass response than some other tubes I've tried, but that’s not a bad thing in a Fender 4x10. Highly recommended!
If you are going for 80's rock lead tone don't buy these. They are balanced and good, but were not special in a mesa 50 50 for scorching lead work or tone.
Tremendous Tone and Well Built
by Doug Robertson
This is the best current production 6L6 on the market, I swear. I've run a pair of them, on and off, in an Allen Accomplice, and a quad in a Mesa Electradyne. Both amps are at their best with these in them. The Electradyne goes from Twin cleans to fairly high-gain, and these Preferred Series 6L6's excel across the board. Highly recommended.
The Real Deal!

Three words...Oh My God. I changed out the Tung Sol's in my Rivera Venus 6 and BOOM! The amp sounded so much clearer. Like someone pulled a blanket off the speaker. Outstanding service and incredible quality. Highly recommended for rock, blues, country, worship, etc...
These are really great tubes. I use them everytime in my 71 Fender Twin Silverface. On a side note I commend The Tube Store's excellent customer service. They sent me the wrong tubes on accident (which has never happened to me before) and had the correct tubes to me in two days, before I sent the wrong tubes back. A+ guys!
