Voodu Valve Tube Change

I know that the original tube of VV is Jan GE 5751, which has 70% lower gain than 12AX7. But, there was a MESA 12AX7 tube in my VV. So, my clean sound was dirty, and gain had too much noise.

I ordered 12AT7, 60% lower gain than 12AX7. Groove Tube - Selected.

I installed the 12AT7 tube on my VV. As expected, my VV's clean and gain sound became perfect!!!
