Has anyone ever used a company called vacuum tube values to purchase vacuum tubes?

I've bought some small signal tubes from Vivatubes and the pair was not matched and test measurements were off. The Gm and Ip of a single 12AX7 did not match the stated values.
I know Viva is a popular dealer, but that's my experience.

I have not bought vacuum tubes from them, but I did just purchase two capacitors to upgrade my speaker crossover. They arrived as described in excellent condition. I am very pleased with the transaction. And the price was excellent.

if that is the case, I would trust him. He lives in my city, in a very nice section/house near the Lake. I’m very familiar. I purchased my Gold Lion 12AX7’s from him. Asked if I could come pick them up, but he went ahead and shipped them literally across town anyway. I can understand his need for privacy, but bottom line, a good guy, fast response, and received what I ordered. I would not hesitate to buy from him again.

Just bought a NOS Mullard  6201/12AT7 from Upscale for a pre I just picked up .   I selected "Kevin's Stash"  and it was worth it. Matched triodes , super quiet and big open sound .   

Bought a few NOS from Brent Jessee in the past and they were the premium tubes described...   

I think its wise to buy power tubes from a place that burns them in and matches.    I did this with the KT88 Gold Lions in my mono amps.  I can't even tell you how old they are.... they were in use a few years, then became the "back up" set .  I had a matched quad of EL 34 where one failed, the KT 88 back in,  eventually got KT 77 quad , one red plated . Then the KT went back in... have been in a few months and still sound great, match pretty tight still.   The 34 and 77 were "matched" at time of mfg.
