Smooth as silk
This should tell you how GREAT these sound - I had bought a matched set for my 76 Fender Deluxe Reverb about 10-11 months ago. Then last week one of the tube failed- burning a screen grid resistor and two 100k resistors at the pilot lamp. Tho with my level of expertise, I probably shouldn't throw full blame on the tube. Those resistors are going on 40 years old.. ANYWAY, point being, despite the last one's fairly short life span, I am ordering a replacement set of the exact same thing because THE TONE IS LUSCIOUS!!!!
