Coversion of existing Leak
pre-amplifier to passive.
Made with high quality 99.99% pure
This listing is for the work required to convert your own Leak pre amplifier
into a passive unit and does not include the pre amplifier. You will either need
to use your own, or purchase one from either myself, or elsewhere.
Any one who owns any of the Leak pre amplifiers will know how poor sounding that
they really are. Even if you spend loads of money on special components, they
still sound poor. This is mainly due to the EF86 tubes that these pre amplifiers
So, after years or wondering what to do about this, I finally came up with an
idea. Convert them to passive. This is done by removing the old circuit board
and valves plus all the old wiring.
Owners of Leak power amplifiers will know that they need very little gain for

work superbly with passive devices.

I use only the finest components for this modification, including 1mm 99.99%
pure silver wire with PTFE insulation throughout as well as high quality Alps
stepped attenuators and Rhodium plated phono sockets. All electrical joints are
made using silver solder.
The pre amp has 2 outputs,in case some one wants to bi-amp or even bi-wire.This
pre-amplifier has 4 inputs.
Most of the controls are for decoration purposes only and do not work. To remove
these would make the pre amplifier look rather odd! The only knobs that work are
the top far right (volume) and top left (switch). This has been done to retain
the Classic look of this control amplifier.
This particular one is being sent to Hifi World magazine to be reviewed, so is
not for sale.
Please remember, the buy it now price is for the modification to your existing
