TUBE GAIN


I currently have two QuickSilver line stage pre-amps. They both have identical gain. One uses 12AX7 tubes, the other uses 6922 tubes. The one with the 12AX7 has loud volume at 11 o'clock and the 6922 the same volume is at 2 o'clock. Is the 12AX7 a more higher output tube than the 6922 tube? I prefer the volume output on the 6922 tubes. Can this be corrected?
Thanks,

If you prefer the gain of the 6922, you can try using 5751 instead of 12AX7. The 5751 is a direct replacement with an amplification factor of 70 (not as low as the 6922 but still better than 100). Besides, all of the 5751 I have tried sounded fantastic.

The 12AX7 does have higher output but for the same reason it is also noisier.
I would check with Quicksilver first.

5751 are not drop in replacements for 12AX7 in all applications.
