Tube vendor recommendations?

Thanks for these suggestions. 

Another vote for Andy at Vintage Tube Services. Always nice, honest and reliable, and great, well tested tubes.

It’s seems as though Andy and Jim are popular choices here. I know that Kevin at UpScale prefers to serve his customers. Two of the products I need tubes for came from my being one of his customers. That said, I’ll likely call Andy or Jim first. 

Haven't dealt with tubes for a few years but when I did I met Jim McShane. He doesn't take calls nor did Brent Jessee. Both are #1 as far as service. I think the reason Jim doesn't take calls is when I met him we could have talked for hours about tubes and audio. Never dealt with Andy but as you can see he is also highly recommended. Never dealt with Kevin either but Jim said he is a good friend and very knowledgeable.
