As some of you might have noted, based on my recent posts, I've been looking for some high quality tubes for my upcoming Moth headamp. Well, I've spent MANY hours wandering the net looking for good dealers and the tubes I want. I came across the Vintage Tube Services site, and picked up the phone and talked to Andy Bowman there. What a pleasure to deal with, and what an incredibly knowledgeable guy. I must have spent at least forty five minutes talking tubes with him, and learned more in that conversation than in all the researching previously. Andy has hooked me up for the tubes I want and I couldnt be more pleased.
He is a great guy, impeccably honest and truthful, and as noted, unbelievably knowledgeable. He was able to advise me on exactly what I needed, based on the sonic signatures of the various tubes in question and end all of my unknowns. HIGHLY RECOMMENDED! And what a relief with so many marginal dealers out there trying to sell you things you have no idea about, in terms of accurate representations.
This company has been in business for fifteen years, and tubes are all he does.
Vintage Tube Services is located in Michigan, near the center of the Head-Fi universe. Take a look at their website, and the equipment used for testing, they may be in a class by themselves in that regard alone.

oh, and dont be too concerned by the 2001 date on the listing, Andy's take on that was that its just too hard to keep a running inventory of all the tubes he has, has just bought, or sold.
