What's the deal with Vintage Tube Service?

Other than RAM I know of nobody with better test gear for tubes than Andy... he has my CC also, reasonable on shipping time imo ... and the typewriter invoices always crack me up :-)
Yes there are other vendors - always good to have depth on the trusted tube supply chain bench 

the typewriter invoices always crack me up :-)

So true. I have a folder filled with them.

Andy is a bit forgetful at times , and doesnot do work or a schedule or a timely fashion Andy is probably 70 now .
if a problem Brett Jesse or audio tubes  .net 

Yeah, Brent Jessee is quick...usually by the next day and he uses PayPal. Not cheap, but you can trust what you're getting.

I've bought from Brent Jesse and Viva Tubes with good results. Nice to have options, although Andy has some rare stuff that I couldn't find there, like NOS 46s, he was going to look in the warehouse for about two months ago...
