@petg60 ... the 6H30 will not work in the VK-33 as it is a 6922 based preamp. It will work in the SE version, which I didn't purchase, because I wanted the option to tube roll and am not a fan of the 6H30. Nonetheless, I have a wide variety of tubes with which to play.
Gold or Platinum Grade of Tubes for BAT Preamp.
Hi, all. I am awaiting delivery of my BAT VK-33. I’m going to replace the 6 stock EH 6922s with the NOS Rocket Logo 6H23-EB, which is a direct replacement for the 6922. My tube vendor has gold grade or platinum grade (which is about $15 more per tube than the gold grade). Tolerances for matched gold grade are 15-20%, while the platinum tolerances are 10% or less. Given that these are small signal tubes, is the tighter tolerance of the platinium grade worth the $$? Is the BAT hard on tubes, thereby requiring the more expensive ones? Thanks for your help.
