im gonna order three 12ax7's for my amp. i wanted to know if i need to order them all matched and balanced or, do only need to get one matched and balanced for the phase tube and the rest can be regular?

They don't have to be matched! Thats the beauty of preamp tubes. Don't know about your particular amp. But usually you want a balanced one for the phase inverter postion. Thats really all you should need to worry about.
If you start a reply with: I have never played one but I have heard good things about it! Your opinion is invalid.
