Is Gold Aero still in business?

They are long gone at least for 10 yrs now. They used to upgraded tubes for Mesa Baron tube amp back then when I was one of their dealers.

I remember them well, still have some of their tubes unused in a drawer somewhere I think. I always thought they were a marketing firm rather then a manufacture; that is they commissioned tube companies to make tubes to their specifications. But it has been a long time and this may be incorrect.

Good luck.
