GE-Style 6L6GC with a short bottle and black plate.

The Classic Sound of the 1950s and 60s - Excellent Tone, Maximum Lifetime!

The perfect choice for vintage tweed and blackface amps such as the 1960 Bassman, Twin, Showman or Super Reverb. The complex midrange and sweet heights are a class of its own. The TAD 6L6WGC-STR is our recommendation for classic tone with warm cleans and rich, sweet mids when pushed. Great for fat jazz or blues tones.

The TAD 6L6WGC-STR is a remake of the small bottle GE6L6GC and has the same warm lower midrange and silky top end as the classic GE versions of the 1950s and 60s. Like the historic RCA 5881, this tube features exclusive blackplate anodes and a side getter. The TAD 6L6GC-STR and the TAD 6L6WGC-STR have our exclusive black-plate desings, gold grid wire, double getter construction, no-noise filaments and 1.2mm thick heavy duty glass. This tube is only 80mm high (without pins) and can replace 5881 or 6L6WGB tubes.

Over the years, my main choice of power tubes has always been the TAD 6L6WGC. I think the reason is that TAD 6L6WGCs are long-lasting, rich in 2nd order harmonics, exceptionally quiet, possessing an abundance of clean headroom, and comparatively low cost compared to other NOS tubes. My current amp is a Brunetti 35W Singleman 1x12 combo, and although the stock tubes were Tung-Sol power tubes, the Tung-Sol tubes wore out sooner than my experience with TAD tubes, and for that reason, among others, my choice has been TAD 6L6WGC power tubes for all my amps that are 6L6-based.

Over the years, I've grown accustomed to the superior quality that TAD 6L6WGC power tubes offer...high headroom, extended lifetime, smooth overdrive response when pushed towards breakup...I've heard other power tubes, but none can compare to the quality and value of TAD 6L6WGC tubes...

These TADs were great. Got rid of the treble spikes, nice and smooth.

TAD 6L6WGC are my favorite 6L6.They truly sound like G.E/RCA short bottles.They sound great in my 66' super reverb and my 74' pro reverb.

I have to say I'm impressed with the mid range of theses. I play a strat through a beefed up bandmaster reverb. The amp is now a combo, with a real 76 super reverb op transformer, Jupiter red caps, a 15 inch Jensen Neo. Mostly all nos pre tubes with a rca long gray plate d getter in v1 vibrato channel. I have had my ups and downs trying to get this amp to sound good, from a d130 speaker, different tube rolling, and finally with these 6l6's, the pre tubes, and a real important aspect a rca 5as4 rectifier, my plate voltage is still 450v, :( it is a joy to play, I find myself unable to put the guitar down. I don't even need any pedals as these sound great on 2, use your attack on the strings to get these spanking.
I have nos 6l6 sylvania but those days are over. I have a few jem amps with all nos stuff but this amp is for playing. Thanks Tube Amp Doctor for a great user tube that is super fun to play! I will be stocking up. And of course the great service I get here at Antique Electronic Supply!

These tubes sound beautiful
To me the sound is expensive vintage on affordable price.
All the right harmonics in all the right places.
Cross between RCA blackplate and JAN 6L6WGB/5881.
Adds a nice depth and sweetness to your tone.

Disclosure: My gear: Gibson Les Paul Special and Fender Telecaster, played through the clean channel (only) of a 12 year old made in the USA Fender Hot Rod Deluxe with a Celestion Vintage 30 speaker, and upgraded capacitors. I have played all the old classic Fender, Marshall and Vox amps over the years, and my sounds live in the range of jazz, blues, and classic rock, with some punk and Foo Fighters territory.

Ok, here goes. I LOVE my new TAD 6L6WGC (short bottle) tubes. These replaced my Winged C 6L6, which apparently are no longer in production, and so now being sold as NOS at the price of a kings a fortune. Let me compare the two...

The Winged Cs had a huge sound, and by that I mean they are loud tubes, AND the bass and treble are as big as the mids. Whole band in a box. The mids are in fact harmonically complex (as they are famously famous for) such that when you overdrive them, and especially when you add some pedal grit, these tubes compress a lot, and the distortion swirls with lots of harmonic crazy complexity. I enjoyed playing them a lot, especially when playing alone in my living room. Which brings me to the drawbacks of the Winged Cs. First of all price. Wow. Second, those fun swirly mids may just add TOO much color. I noticed the difference between various pedals seemed lessened as these tubes added so much color of their own to the mix. Lastly, the big fat rich bass (which seems so great when masturbatorily jamming away in one's living room), when placed into an actual band setting with OTHER musicians, and live, sounds boomy. Not loose (at least not loose through a punchy speaker like the Vintage 30) but boomy. Just too much bass, and when dialing down the settings on the amp, the bass cannot be pulled down enough. This all is more of an issue when playing live, and with other musicians.

Which brings me to the VERY nice discovery that the TAD (short bottle) 6L6 represent. The TADs are MID-focused. YES they do sound a lot like the old RCAs (which were mid-focused too). Mids are where the guitar lives hombre. In my experience, players who say they don't like much mids, or dislike a MID HUMP, are often the players whose playing is confined to solo self petting in their living rooms. Or they play a style which calls for scooped mids, or massive bass (that is legit of course, remember my sonic range noted above). Live players seem to better understand that mid-focused tones cut through the mix, works with the bass (doesn't step on it) and compress and crunch more convincingly. So the short bottle TAD 6L6s are mid-focused. There remains plenty of great bass too. AND the highs are clear, but NOT ice-pick, even with the Tele (I had found the Winged Cs to make ice picks, and pulling down the treble controls did not tame the ice pick until the point of muffled tones). The EQ is just so much better balanced. Lastly, the harmonic complexity of the TADs is plenty rich, satisfying and musical (!!!) without adding the excessive color of the Winged Cs. Musical harmonic richness is important to me, and these tubes have it. I find the JJ's too sterile (no color in the mids). The Winged Cs too much color. And now the TADs just right. I am 100% happy with these tubes. No need to seek out dwindling stocks of old RCAs now.

Power wise, these have more clean headroom than the Winged Cs (mine broke up quite early). These break up in the middle of my volume settings, and they break up in a very musical way. I feel my cleans are better now, while my overdrive crunch more REAL and convincing. Bias note: I bias my own amp. I experimented with a range of bias settings between 65 and 78 millivolts. To my ears the best sounds sit at precisely 71.8 mV.

I should have bought a matched quad to replace mine on the fly if they die at a gig. However, every TAD tube is labeled with its actual power tested ratings (in Germany) so I think I can order two more with numbers to match my recent purchase.

I cannot speak to the longevity yet. They are too new.

In short: if you play classic mid-focused guitar tones (and unless you are playing modern brutal deadly types of metal) you should be, I HIGHLY recommend these for their classic RCA like mid-focused, musical, balanced REAL guitar tones.
