Vacuum Tube - 6L6WXT+, Sovtek
Higher in gain than the 5881WXT, with full base. Modelled after the vintage RCA 6L6GC "blackplate," the Sovtek 6L6WXT+ features larger plate dimensions and improved grid structure for increased power handling capabilities.
The 6L6WXT+ also features mica spacers with metal springs to eliminate tube rattle and microphonics. The Sovtek 6L6WXT+ yields a 20% higher output than the Sovtek 5881WXT and offers superior tone and overall performance to any 6L6 or KT66. The ultimate 6L6, the WXT+ will improve the sound of any 6L6 guitar amplifier.

Product Reviews
Great price, great tubes, order came in quickly.
Bought a quad "apex matched" set of these and they failed immediately upon installation. Figured it was the amp (Peavey VTM 120), took it to my local tech who confirmed my VTM was functioning properly and then confirmed that the tubes were dead on arrival.
Much better than what I had in my amplifier. Basically replaced stock tubes. Sounds great! Should last me a while. I picked these because many have stated that Russian tubes are best.
My Peavey Encore 65 was humming worse all the time. I put the new Sovtek 6L6 WXT and all quiet now. Huge difference. Great price fast delivery.
