Thanks. I've got some RFT 12ax7. I need a third. What matches up well with them in your opinion ?RFT is darker and breaks up sooner than Brimar or Mullard. Telefunken or Amperex are a bit brighter and bit cleaner, and a bit cheaper. ANOS tubes are a better way to go than NOS IMHO, as long as you're getting them from someone reliable. I think that some folks like Sylvania for those amps as well.
Power tubes-Siemens are less expensive than Mullard, although not cheap any more
I've found the first tube most important. Definitely put an RFT there. Second tube less critical, needs to be a decent tube. Last tube overdrives when the power tubes start to cook, so an RFT there as well, IMHO.Thanks. I've got some RFT 12ax7. I need a third. What matches up well with them in your opinion ?
