    Finally broke down and ordered some new tubes for my VAC

    After lots of reading and asking for suggestions, I settled on Matched Sets of Genalex Gold Lion Gold Pins in both 12AX7 and 12AU7 to retube my VAC CLA1. The current tubes I have were purchased from VAC but at least one of the AU7s is very micro-phonic and I am not getting what I want out of the no-name Chinese AX7s. The Jan-Phillips AU7s are OK, but I am being told I am not at the full potential of this Pre with the current cheaper tubes. I got each matched set for $75 and hope to have them before the end of next week.

    Congrats on the tubes. Give them about 25-30 hours of break in. They will sound rough at first.

    I'll be interested to see how you like the tubes. My pre has 4 12AU7's and I could use a new set to roll.

    Jack,

    My pre uses both sets in normal or high gain, but only the AX7s if in passive Buffered mode.

    Got my tubes last week and have about 20+ hours of music time on them now, so not fully broken in yet. But, the improvements are easily noticed. The bass is still a little congested, but I now have much more bass than ever from this setup. The detail, separation of instruments, and quieter noise floor / background are very noticeable.

    Great tubes for the money for sure!

    Glad to hear the tubes worked out for you. It is always a crap shoot. I am hoping that I don't get the urge to tube roll in my new Cary DAC. You can drive yourself crazy rolling tubes in search for the holy grail of tubes.
