Check out the tubes in the Alpha. Lots of times these tubes, when changed by prior owners, can have too high a gain, such as EI 12AX7's (no longer in production). I believe it is possible to use a 12AU7 or a 12at7, which have lower gain. I use new production Mullard 12AX7's (or JJ 12AX7's in mine. I preferred the Mullards.
If you like their tone as is, then you can get an in-line attenuator which will reduce the gain but not change the tone.
Hope that helps a bit.
