Ratings & Reviews
I've used these for years on my Fender Bassman �300. The most powerful amp I have ever owned. �The sound was organic and 3D. Much better than�stock Sovtek. I used a ring on them which reduces �vibration and micro phonic effect, because you �know a bass amp is not a picnic for tubes.�This application is rough time and this amp played�in studio almost everyday but did not get out �much. The tubes suffered about 2 years of this �abuse. Not bad! I'm telling ya, it's rated 300W on �the back of the amp, but when those tubes glow, �the lights are dimming. That's the juice they can �take. Compared to a solid state amp, 6 of those �tubes can produce equivalent of 900W. Nothing�sounds like tubes.
