Report Review for product Vacuum Tube - 7025, Tube Amp Doctor, High Grade

Excellent tube , I'm using it in a Marshall AVT 150 , which is not known for impressive overdrive , but with this tube it greatly improves the clean and overdrive channels , also if you put a tube screamer in front of the amp , you get very satisfying overdrive on low or increased gain . and of course the AVT 150 will crank out 150 watts ,
This is my new go to tube for the Marshall AVT 150H , it takes the place of a regular 12AX7.
