The new Brimar are still gearing up to produce their own valves (small batches), they are still in the process of overhauling tooling & machines, along with wiring everything up etc, etc. As you could imagine, it would be no small project. And then this damn COVID-19

thing has slowed work with only a skeleton crew working on the project now. I know we all hope they succeed.
I think it's entirely possible that the USA could produce valves/tubes that would surpasses the current offerings, most definitely. As good as in the heyday without breaching EPA laws, kinda hard to say (y'all could farm "those" processes out to Mexican subsidiary plants). The thing is, no current manufacturers use the "old" cathode coatings, plate coatings etc etc, but that's not what's making the tubes "lesser quality". These guys now are cutting corners all over, use lower quality components all over & quality control is, well, low quality. I mean, just visually compare an old tube to its same new production counterpart. Thinner grid support posts, thinner Mica supports/spacers, poor crimping etc etc. Destructive testing shows thinner glass, plate materials etc etc. Without going on a big (or "bigger") rant, I'm sure y'all get the picture. If they let all these things slide there's a good chance they're letting everything slide, all the while telling us it's a reproduction of your favourite "old production" type. Tubes that previously would not made it through quality control & been discarded are now being shipped. If your supplier doesn't test properly to weed out the

we end up copping them. The last "decent" tubes were the (Saint Petersburg) SED Winged C's. Could the good ol' US of A produce tubes to rival the SED Winged C's??? Damn straight they could. Cheers
