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


Hi. I need to purchase 36 Golden Lion kt88 tubes. It looks like the average cost for that would be about $1,600. I ran across a company called "Vacuum Tube Values" where I can get them a couple hundred bucks cheaper. Has anyone had any experience with this company? I have seen discussion to be careful about buying from a non reputable dealer because you can get less than top-quality tubes?

I just looked up cost on this which is always a wonderful reminder of how dreadful margins are on tubes.  I am not going to tell you my cost but will say that $1400 or below would suggest to me these are not new or there is something off.  

$1600 is a very fair price.  You best bet is buying from someone like Tube Depot.  
I have three Cary V-12 amps. One stereo and two mono blocks. They power Aerial 10T speakers. The stereo amp powers the heads and the monoblocks power the bottom cabinets.
RAM tubes without a doubt….grading, screening, matching system , computerized curve tracing setup by a tube amp genius, the late Roger Modjeski ( yes I have 16 of his KT88 )
