I'll only say this, if you want to GET what you pay for, sometimes, often less. Andy is the best vendor I've come across and I've dealt with virtually all of them at one time or another, several NEVER again. He has great testing equipment and he KNOWS his tubes. "Never let the truth get in the way of making a buck", NOT Andy. The guy is as much a hobbyist as a businessman preying on the unwary like some of those guys. NOS tubes have become a cottage industry and it is important for the novice to be cautious lest they fall prey to the unscrupulous. It's easy to get ripped off.
