After extensive research and engineering, New Sensor Corp. has reissued the famed Genalex Gold Lion CV511 (6V6GT) vacuum tube.

From our review of this 6V6 power tube: "The Gold Lion 6V6GT/CV511 tube is the top of the line in current production 6V6 power tubes. To go on about the subtle tone variation would frankly be a waste of time. They have the classic 6V6 tube sound. Plenty of smooth creamy overdrive. You won’t get better tone and reliability from anything else on the market. If you want even more then look for NOS tubes like Brimar U.K., Philips, or RCA.

Genalex - Gold Lion 6V6GT / CV511 | Worthy upgrade for DRRI but note your bias settings.


I retubed my 65 DRRI with all Genalex Gold Lions. They sound excellent clean or overdriven and play great with pedals. One thing to note when biasing the GL-6V6's on a stock DRRI is that with the bias pot wide open, the max I could bias these was at about 64-66%. They sound great there though I normally run at a bit above that point. Fender biases these amps at about 50-60% which is too cold for some. If you prefer to bias above 65% give or take, you'll have to swap out a resistor with these to change the range of adjustment.

Genalex - Gold Lion 6V6GT / CV511 | Very Happy with Genalex Gold Lion tubes


Bought a pair of GL-6V6 to replace the original GT 6V6 in my new Princeton Reverb Reissue. Did a complete swap out of the original 12AX7 preamp tubes with Genalex GL tubes too. First time using Genalex tubes and have had no problems. Very happy with the Genalex Gold Lion exceptional clean, warm tones with no noise.

Genalex - Gold Lion 6V6GT / CV511 | Smoooooooooth


I can't compare them to NOS tubes because I've never owned them, but I can say the GL-6V6 sound great. I play mostly clean R&B and jazz. Nice across the entire frequency spectrum and smooth, not brash.

Fantastic harmonics


I've been searching for the magic tube combo to run in a '58 Champ clone that I built about a year ago. This is a class A single ended amp, meaning one power tube has to do the work of two. The kit came with a JJ 6V6 which is a good sounding, long lasting tube but I always like to experiment. Without going through all the details about trying different AX7s in the pre-amp (tested quite a few) The best combination I've found is a TAD 5E3 rectifier, a JJ 12AX7 short plate plain pin, and the Genalex 6V6 output. No info on lifespan of this tube but is was compared to a TAD 6v6(junk with the bottle attached to the base crooked and the bottle snapped off in my hand the third time I was installing it) and the JJ6V6S. Although the JJ is a fine tube(and I used a brand new one for test) the Genalex beats it in detail, clarity, tone, and extremely low noise. Harmonics are out of this world. I have 6 other amps, all of which are A/B and have 12" expensive speakers. Celestion Alnico Blues, Jensen Alnico, etc. The Champ has a little 8"Weber Alnico vintage in it and for quality sound and tone it can stand it's own against any of these other amps when armed with the Genalex output and JJ pre-amp. This combined with being small and light has now moved the Champ to my favorite go-to amp. Have ordered a matched set to go into my Princeton Reverb Ltd. Edition that has a 12" Jensen Alnico. Expecting pure bliss. If these tubes even last half as long in the Champ as the JJ did, then these will be what goes in it from now on even though they cost more than twice as much. I've never been able to get warmer, creamier overdrive out of anything else like this. Blues is my flavor and Genalex I favor.

Very rich sounding


I've had a pair of the Gold Lion 6V6GT tubes in my Deluxe Reverb for about four years and they have never given me a problem. They have a nice complexity to their sound and are very warm. I run them clean and use pedals for overdriven sounds. Worth the few extra bucks.
