Metal-base and non metal-base 5AR4/GZ34?


Sonically, what's the difference between the metal-base and non metal-base 5AR4/GZ34 rectifier tubes, Philips/Amperex or Mullard? Especially as they perform in the Modwright 9.0 SE preamp?

had to cut a hole in the cover to accomadate the size,but Im very happy with it. Got mine from a guy in Holland thru ebay for less $.
