Notes

Leak produced very high quality audio amplifiers before WWII. Starting in 1946 Leak produced a series of Hi-Fi products with low distortion and excellent frequency response. Leak Varislope filter is not included. Baxandall tone control circuit used. Uses two EF86 valves. The low distortion post WWII Leak Hi-Fi amplifier products preceded the introduction of the famous Williamson low distortion circuit.
