Be sure you have the 12AU7 and the 12AX7 in the proper positions. . .

Well it should have as I understand it. If all tubes are in the proper positions I'm mystified. A call or email to Steve is probably in order.

I'd first put the original tubes back in and make sure the amp is working correctly at the correct volume.  Then substitute one new tube at a time.

Well, it's odd that you had that problem but glad that the full volume is back!

FWIW it sounds like one (or maybe both) of the new 12AX7s are bad.
