GT-KT66-C Duet

Chinese made copy of the classic KT66. Great sounding - one step down from the KT66HP, but less money too.

New and exclusive GT design. An exact copy of legendary Gold Lion "valve" from the Eric Clapton "Blues Breaker" Marshall combo. Big fat bottom, crisp highs, very warm and a springboard response that make playing fun again! Highly recommended for Fender type amps.

GT-6V6-C Quartet

Classically designed with warm overdrive and soft distortion character. Chinese made copy of the old USA 6V6 we loved in our old Deluxe Reverbs. Round, warm, fat tone with lower power put great for a soft blues tone or great fat classic rock sound too.

Country of origin: China

  • These Look just like GEC KT66

    As reviewed by solerso on 3/18/2011

    But I am now using the "Genlex" KT66 made by New Sensor. The Shaugang is the stock part in Marshall Vintage Moderns and I used those tubes in my VM for over a year. Filament hum was always a minor issue freom day one but it got replace-the-tubes-time annoying after a year. I bought a set of Shaugang (because all the chatter on the VM forums was that all other KT66 were crap "shaugang rules" etc..,)I also bought a pair of Gold Lion KT66 becasue looking at them i noticed two design improvements - the plate structure is mounted down near the base and they dont have those small confining plates waving like flags on top of that.OBVIOUS structural improvement. Everything else being equal the Gold Lion tubes will last longer and run quieter, and they have. They dont look like GEC's but really, who cares?
