So the tube guru in our group gave me a few driver tubes to roll into the center position of my ST-120 and I wanted opinions and advice. He thinks there may be sonic benefits. Here is a list:
1) E180CC (IBM 5965)
2) 6829
3) 12AU7
4) 12AV7
Any opinions as to pro vs con? Also, can I exchange the center tube for any of these without damaging the amp? Lastly, do I need to turn the amp off before swapping out the center tube or can I just pull it and replace it "on the fly".
Thanks in advance.
Dave
