I think like a lot of people here I used to get my tubes from Laura at Valve Queen, but ever since she switched ventures (all the best to her and the shift) I've had a lousy luck with some other companies. I've had matched quads of power tubes arrive that weren't even remotely close to being matched, and received some super microphonic preamp tubes. Who are you guys using these days that actually tests the tubes before they ship them?
