I'm about to buy a pair of 6bx7gt's for my old skool toaster MPX3. First of all, will it's psu even be able to handle them? Second, what are some good ones? I'm probably gonna buy them matched from tubeworld.com, if there's a better dealer that takes paypal tell me!
Would you recommend the "O" or "D" getter halo tubes? And what brands? They seem to recommend the GE branded amperex and RCA tubes, but then again they're selling them...
