LP-PRE – Two-Channel Preamp Kit

CAD $46.00CAD $233.00

Description

LP-PRE is based on London Power’s STANDARD Preamplifier presented in our book The Ultimate Tone (TUT1) and used our own amp line. The clean channel is distinctly warm and “North American”, à la Fender. The lead channel can be tailored for a wide variety of crunch and distortion sounds, up to 1970s saturation levels – anything from Marshall crunch to “modified” saturation. Any 12A_7 types can be used, with maximum gain achieved by fitting two 12AX7s.

Local supply decoupling is included. Channel switching can be provided by use of our Electronic Relay Kit (ERK), or through use of two of our RLY relay kits.

The board has silk-screening on both sides which allows you to stuff the components appropriately for INTERNAL or EXTERNAL TUBES. For INTERNAL, all the components are on the same side of the board; for EXTERNAL the components are on the opposite side from the tube sockets.
