Product Code:


Add PRE2-BLT to your order of a Tube Preamp that uses two tubes, to obtain that kit pre-assembled. This applies to:

 - D-PRE
 - M-PRE
 - Z-PRE

Add 1x PRE2-BLT for EACH two-tube preamp of your order which you would like to receive pre-assembled. If there is more than one two-tube preamp in your order but you would only like one of them assembled, add PRE2-BLT and specify which preamp should be assembled.

Assembly includes only those components that mount to the PCB. You will still have to wire the pots and jacks to the board.
