Do all mini tubes (6DJ8, ecc82...) manufactured by Mullard flash, regardless of brand? For example, would a Philips tube manufactured by Mullard in either the Blackburn or Mitchum plant exhibit the flash, due to the same construction? Or, are Mullard branded tubes constructed differently than Philips branded tubes manufactured by Mullard...even if both tubes are made in the same plant?
Mullards for Preamp?
I have a Cary SLP-74 tube preamp and just replaced the original Chinese tubes with Mullards. When I turn the preamp on to standby the two output Mullards flare up and then go down. Is this normal? They really sound amazing as compared to the ones that came with it. Very warm and lush sound. Just what I wanted. I just need to know if they are supposed to do the flare up thing? Thanks for any help. -Durr
