I no longer use my trusty NOS Mullards (new amp, different tubes) but for me the best thing by far about those tubes was the flash at start-up. Sure, they sounded great, but it's that flash…oh yeah…uh huh...
Brimar vs Mullard cv4003/12AU7
Has anyone heard these two NOS tubes pitted directly against each other. The virtues of the Mullard are well documented; certain sellers (cough, Upscale) praise the merits of the Brimar to the heavens, and they *are* considerably less expensive. Thoughts?
