Leak Stereo 20


The Leak Stereo 20 may be fed from the Varislope 2 Stereo preamplifier or from any other suitable source.

The Leak pre-amplifier is supplied with a grey or brown multiple cable terminating in an octal plug which fits the socket on the Stereo 20 marked Pre-Amp and automatically makes the input connections.

When a different pre-amplifier is used, the input connections should be taken via two screened co-axial cables to the plugs fitting the sockets marked Input L and Input R.

Source impedances higher than 25,000 ohms will tend to raise the hum level above the advertised figure of 80db below 11 watts. An input of 125mV rms will give a power output of 11 watts.


Valve complement: 4 x EL84, 3 x ECC83, 1 x GZ34

Year: 1958
