I know Jon. He is a good guy. He is on the road most of the time looking for vintage equipment and vacuum tubes.
He had many of my Mullard Long Plate 12AX7 and Sylvania VT-231 tubes.
There are many excellent tube vendors, across the US, that supply dealers, like Jon, with vacuum tubes.
You can go directly to them and save $$. > Same tubes for less money. Yeah!
Most of these suppliers would love to have some business as they are sitting on big inventories of the tubes that are in demand.
I believe the site rules do not allow to name vendors if they are not a site or vendor supporter. I see this rule overlooked on many posts.
Most of these vendors are not known or are frowned upon because they sell on venues where tube quality is assumed to be lacking or non-existent.
These vendors have tubes with quality that equals or surpasses the current offering.
Many of these tube sellers either stay away from this site or are lurkers. They simply cannot talk about their systems and toys because they have a business that could be tied to the post.
Apparently Jon is a approved vendor so we can mention his business.
