Leak Logo Leak Varislope Stereo
Pre-Amplifier
 

This pre-amp, and its companion (the Point One Stereo) are quite viable for use today. Although best peformance is not acheived unless the circuit is modified so that the signal to noise ratio is improved on "high-level" inputs. (A short description of the required modifactions is "under construction"). The unit above has the Brown and Gold finish, with the front panel being made from "diakron" plastic (not unlike perspex).

The pre-amp was also marketed with a fantastic looking gold-anodised front panel. This is shown below.

Technical Summary:
Effectively a stereo version of the Varislope III. Original issued in the same gold and brown livery as the Varislope III. Later the name was updated to "Varislope 2 Stereo", and the finish was revised to the 1960's "silver an grey" to match the new transistor amplifiers from Leak. The circuit uses four EF86 valves shared between channels, with facilities similar to the Varislope III. 3.5mV sensitivity on Pickup input.
