Tube vendor recommendations?

Andy of Vintage Tube Services

I've used Brendan at Tubeworld for a long time, but have done business with Brent Jesse, and he's good. I like the Tubemonger too- he gets some offbeat tubes - never used flying lead type converted to conventional pin and socket type. Andy I've heard of, and Jim is a new one for me, who I'll check out. 

RAM Labs for me too. Roger Modjeski has a vast knowledge of tube design, construction, and performance parameters, as well as amplifier circuits. He often provides tubes to other amp designers such as Mike Sanders (Quicksilver Audio) and Ralph Karsten (Atma-Sphere).

Jim McShane is fantastic and can be highly recommended. It’s a shame that his web site looks like it was kludged together by a six year old child who had been drinking black coffee all morning.

Thanks for these suggestions.
