Finally in production after 3 years of intensive research.

This all new TAD 6V6GT-STR combines the exceptionally sweet characteristics of the NOS 6V6GT by RCA or of the GE 6V6GTY. It is a heavy duty 6V6GT tube, which can handle a higher plate current.

This TAD 6V6GT-STR caters for a detailed and powerful tone and an abundance of sustain; characteristics you would only expect from the finest NOS 6V6GTs from the 50s and 60s. Even when pushed into saturation there are no harsh upper mids, which is frequently the case with other 6V6s. Sweet full-bodied tone with silky highs.

TAD 6V6GT-STR is recommended for all 6V6 applications where a powerful but sweet tone is desired; It works great in amps like the Fender -Tweed- Champs, Deluxe Reverb Amps, Vibro-Champ, Fender Champion 600 or the Univalve. This is also the perfect choice as a reverb driver for the Vibrokings and Dual Professionals.

I had a bad tube right out of the box. Antique lectronic supply handled it and sent me a new matched set. It’s nice to buy with confidence. I’ve had these in a few different amps and they are one of the best new production tunes I’ve used.

3 months later and unable to find a single fault with the amplifier...each one of the tubes that didn't physically get broken has failed.

They are not as robust as they claim.

I have been hearing about what great tubes the TAD 6v6's are, and finally had the chance to give one a try. I'm glad I did! the TAD 6v6 delivers a really nice, "sweet" sound, especially when I'm pushing the amp (a tweed Princeton). I highly recommend this power tube!

Bought a matched quad for my vintage Motorola HiFi monoblocks.

Things went VERY well for the first few months till someone dropped something and broke one. Not their fault. Dropped a spare in and went about life.

13 months later I left for a two week vacation. I came home to find one of the tubes started arcing. On the tester it emits a purple glow with zero emissions.

The remaining tube on that pair made what others told me was "harmless blue glow". It wasn't so harmless. After a few days it flashed over.

So at least one pair out of my original quad prematurely failed. I suspect there was something wrong with the vacuum...even though I didn't see the usual symptom.

The amp has been checked out and all I can find is tube failure.

I finally bought a pair of these for the 61' Brown Tolex Deluxe, having wanted to try them since TAD brought them onto the market. I really like'em. They have the default NOS sounds - like a mini-6L6 at lower volumes and blooming into the so-well known,creamy 6V6 roar in overdrive, like a beehive full of awesome 6V6 overdrive goodness.....Like Groove Tubes, the TAD has tried to bring back a few exceptional tubes from the golden age.This was back- engineered to be a reasonable facsimile of the Brimar 6V6GT/CV511. I think they got pretty close. Of course only time will tell as to durability but they sure seem,and feel like good quality parts. The TAD 6V6 is one of a few current production 6V6 tubes I will use..the other two being the Electroharmonix 6V6GT and the J.J 6V6S. These three stand on their own against NOS, and I have no doubts at all using them right along with even the best Brimars and RCA's in my stash.

I got these tubes for a Tone King Falcon - they were the recommended tubes. The first set I got had a bad tube. Antique ELectronic Supply replaced them for me. The second set was perfect. I think they are great. It is hard for me to see how they could be improved. I collected NOS tubes for years, but as the quality has improved with new stock, I am no longer interested in the minor differences between modern tubes and NOS. These are great. When I use em up, I will get more - from Antique Electronic Supply. They are a good source for modern tubes.

New production tubes have left me wanting and even my favorite 6V6's drift, ping and rattle too quickly and too often. I was surprised when my Louis Electric Columbia Reverb came loaded with EH with a Sovtek 5AR4. EH has been my least favorite glass. Though they work fine in most positions in the preamp section of this amp, their grind and grit was not my cup of tea in V1 or as output tubes. New sets of Tung Sol (my used-to-be favorite new production) have been so inconsistent and have drifted into oblivion in short order. JJ 6V6's sound quite good but not what I'd call sweet sounding, and have experienced inside the glass rattles in combo amps prior, though not in my last set (from AES), which I've stashed.

Enter TAD STR. I've tried the 6L6 STR (this amp uses either) and was very satisfied but long for the 6V6 qualities. When I learned that TAD released their version, designed to be reminiscent of the old RCA and GE but built to handle modern power supply and high plate voltage, I had to try them. I'm here to say I've never been happier with a new 6V6GT, nor has any new offering come close to its full dynamic range and overall sweetness. Bottoms are surprisingly big and tight, highs are bright, and mids are plump and juicy. It took a couple hours to burn them in, even though the select premiums are thoroughly tested.

I've also reached the same conclusion for their 7025 for V1.

All three TADs mentioned still have to pass the test of time in this amp, but so far I give them a thumbs up, particularly their new 6V6GT. Exception being their 6L6STR and 7025, which have been going strong in my Richter RS-33 for well over a year. I'm hoping their 6V6GT hold up as well.

Also, I've been very happy with Antique Electronic Supply's customer service. I don't mind paying a little sales tax to my own state of AZ. They've been great.
