“I bought this tube a little over a year ago, thinking it would be superior to the stock Sovtek that came with the preamp. It blew up after 1740 hours, and from what I've read, these things should last up to 10,000 hours. Glad I saved the Sovtek.”

“This rectifier is for my Modwright SWP 9.0 SE. It has replaced a Brimar, and so far I am glad I made the decision to go with this Genalex. The improvements are in the increased dimension of instruments, and overall realism. In all it is a good rectifier. Buy with confidence.”

“Purchased this rectifier for my Musical Paradise 701 mk2 preamp. It was a nice upgrade, as it had a cleaner sound and added greater separation of performers within the sound stage, I really enjoy this attribute. And there has been a little more 3D effect overall, Very Nice. And the shipping speed surprised me, ordered Sunday evening and received it Wednesday afternoon. Thanks Upscale.”
