Report Review for product Vacuum Tube - 12AX7S, JJ Electronics, Mid Gain

Bought this as part of a kit for my '76 Fender Vibro Champ. Fits, works beautifully, and solved a problem with the speed and level settings of the built in tremolo. Also, the tube kit arrived before the estimated delivery, allowing me to use my amp in a gig I was going to have to borrow gear for.
