Great pre-amp and power amplifier from the golden HiFfi era in England, build around 1958-1962. One of the first stereo amplifiers to enter the market. Completely original, except for the on/off switch, which was replaced by exactly the same type, an two new EL34's. All necessary cables and plugs are included, see pictures. Comes in two parts: One pre-amplifier with two ECC83 valves. Cosmetically it is in very good condition, with (copper, mirror like) aluminium front plate. One power amplifier, with 2 ECC83 and 2 EL34. The original EL34's were worn out and replaced by two new Electroharmonics to test the unit. It is in *original* condition, it is up to your likings or taste to modify the passive or active components to improve the sound, as the parts are all almost 60 years old. The unit is tested and played for about 8 hours without any problems. http://www.radiomuseum.org/r/pye_mozart_hfs_20m.html Power output: 9 watts per channel into 8Ω (stereo) Frequency response: 5Hz to 50kHz Total harmonic distortion: 0.2% Damping factor: 30 Input sensitivity: 0.22V Signal to noise ratio: 70dB Speaker load impedance: 4Ω to 15Ω Dimensions: 260 x 185 x 95mm Weight: 6.4kg Year: 1961 Local pickup possible in Rijswijk ZH, The Netherlands.
