Upscale is a top shelf tube supplier. I've always had good luck with them for my tubes.
Has anyone bought Gold Aero PXB300 tubes from Upscale Audio?
My VAC Renaissance 70/70 is going to need tubes, and VAC is in short supply right now. Plus they seem to be really expensive from them. So I was wondering of getting 4 matched pairs from Upscale? Or is there somewhere else that has good matched reliable tubes?
