The tube He sells clearly a white base tube.? Check this link.? He had them change specs on these and had to purchase hundreds of them to test before they finally got a good batch.? These exceed Eimac spec now.
By the way, Someone pointed out that RF parts no longer have 3-500 tubes listed for sale.? They seem to be all gone from the listings.? There are a few multiple tube sets listed and that's all.? Maybe a website issue or a parts issue.? Not sure.? ?I will have
to check back to see if they show up again.

The tube in the link has the brown base.? That comes from factory #2..... which per JI, has a 70% failure rate.? ( how the hell factory #2 stays in business baffles me).?
?
Factory #1 has the white base...and has minimal tube failures.?
