That is one highly regarded and praised cartridge , you lucky guy ,
While I can't afford a cartridge like that , I can try a 12BH7 tube , thanks.
I'd like to pass on something I experienced with 3 of the same tubes
dated within 6 months of each other 1959/60 , GE long gray plates ,
2 sounded good and one stood out like magic .
You might want to try rotating your tubes to the 1st position or
go a little further and place JJ tubes in 2 & 3 to help isolate the sound of your GE tube while listening for the magic one .
