Groove Tubes: GT-E34-LS

   


 

 

Yes, this is no typo. GT-E34-LS is a special version of the well known EL34.
It has approximately 30 watts power instead of 25 watts. This means a bigger soundstage, more
headroom and therefore less compression as an average EL34.
Even more beautiful: the frequency range is extended in the low-end in a way you can't get by
increasing the bassknob on your amp.
What you will hear is a lower cut off point that works out in a very natural and musical way.
How does a GT-E34-LS relate to an average EL34?
GtrGear tested both in a stereo poweramp and had each powertube type in a channel. 
Switching channels/tubes on the fly. There is simply no comparison between both JJ/Tesla's.
The GT-E34-LS makes your amp sound BIGGER and gives you back the lowend you didn't knew you 
missed it!
How does the GT-E34-LS relate to a GT-EL34-R2?
The R2 is a real EL34 and crunches a little more like no other EL34 does.
The LS is drifting away soundwise from EL34, more leaning towards KT88.
The R2 starts to breakup/compress earlier because of the 25 watts vs 30 watt of the LS.
In the end it's all depending on style and taste. R2 is approx. 30% more expensive b.t.w.
GT-E34_LS has the same size and octal-socket as EL34. It is a perfect replacement of an EL34
without any problem. Just be sure you bias, just you do after every powertube replacement.
