View all Miscellaneous |
MULLARD 3-3 AMPLIFIER of 1959 Mullard in their Book ‘Circuits for Audio Amplifiers’ in 1959 included the Mullard 3-3 amplifier; the book cost 8/6d, and it was an immediate success for amateur builders of the time. The amplifier incorporated 3 X valves 1 EL84 in the output stage an EF86 first stage and an EZ80 as a full wave rectifier. Producing 3 Watts at less than 0.05% harmonic distortion into a 15 Ohm loudspeaker, this was Monophonic sound, two units would be required for Stereo, but this was still in it's infancy in 1959, and Mono recordings were still being sold at the time. This unit was built around 1963 by the author who had later made the Mullard 5-10 amplifier, see item A1646. The author used a Decca Deram ceramic cartridge with this unit. On the front are controls for volume treble and bass, the knobs are not fitted. Add a memory or information about this objectA1647 |
