PIONEER M-73 M73 AMPLIFIER VERY NICE CONDITION,PERFECT WORKING,,SPEC-1 SPEC-2 - $560 - (Mascouche, QC)

THIS IS MY OTHER PIONEER M-73 AMPLIFIER IN PERFECT WORKING AND VERY NICE CONDITION,, ,,SOUND INCREDIBLE,NEVER SAW CIGARETTE OR BAR,EXCUSE MY ENGLISH,,LOOK ALL PICTURES FOR DETAIL,,ITS A VERY NICE AMP,,LOOK PICTURES FOR DETAIL,dual transfo,VERIFY BY A TECH,, ,Stereo power amplifier which adopted 2 power transformers. The 2 steps of ±2 powering and differentials amplification current mirror circuitry and the final-stage parallel push pull pure complementary circuit are adopted as a circuit system. A power-source part is adoption of 2 power transformers which improve a dynamic behavior, and has eliminated the cross interferencee between channels. Moreover, with a stream composition with the capacitor of 12,000 micro Fx4, even if there is a low-pass continuous sound of a large swing, it reproduces with a margin. The large-sized peek power meter with a logarithmic comression circuitry which can carry out the Direct reading of the output is equipped. The protection network constituted from a quick electronic circuitry of a reliable power relay and a response is adopted, and a speaker and a transistor are protected from an emergency outage. Two speaker output-terminals are carried and a play of A+B is also possible. It is the panel design which can be mounted on EIA specification rack.
