Hello; I am looking for any feedback, recommendations, suggestions and experience from owners of BAT VK75 SE regarding tube rolling (6SN7 & 6V6GT). What sound best, make this wonderful amplifier even better or create best synergy with this amp? Any problems with NOS tubes? Did anyone tried Brimar CV1988? Please, let me know. Your help is very appreciated.
You might try the STC Brimar CV 1988. Some call it a Mullard.I use this in place of the 6SN7 tube in my Audio Note amps and the difference was huge. Much better detail and midrange clarity. Bass takes about 100 hours to fully flesh out. So be patient.
