The model AM-35 is built entirely with Japanese discrete transistors, without integrated circuits in the amplifier or driver stages. Only the input equalizer for the phono stage and the tone control stage are each built around one Mitsubishi M5220P low-noise, low-distortion operational amplifier of low integration (two op-amps in one 8-pin package). The Akai AM-35 amplifier has a classic schematic – a push-pull end-stage with fully complementary power and driver transistor pairs, and a differential pre-driver stage. The pre-amp circuit is direct-coupled to Toshiba 2SK170BL J-FET transistors of vanishingly low noise figure. Direct coupling eliminates input capacitors, and the phase distortion they would introduce. The output power is delivered by Sanken 2SC3855 (NPN) and 2SA1491 (PNP) complementary transistors. The output transistors are mounted on a large aluminium heat-sink, and the amplifier case permits good natural ventilation. There is no fan to produce noise. The design with discrete components, direct coupling and fully complementary semiconductors serves for linearity of amplification. Indeed, the sound of the AM-35 is very precise, clean, not colored. The amplifier delivers an increasing power gracefully – without signs of fatigue, such as increasing noise or distortion. The amplifier has a standard set of tone controls and correctors, e.g. a subsonic filter, variable treble and bass controls, and a RIAA-correction of the Phono input (moving magnet). The Akai AM-35 has also a handy input/output switchboard, which enables the playback, record and tape-dubbing without reconnecting cables. With this amplifier, one can: - play a vinyl record and send the signal to a computer to digitally record it; - play a compact disk or cassette and send the signal to record it on a reel-to-reel tape deck. With a 3-head deck, one can listen to the new recording while it is being made; - connect an external equalizer (or sound processor) after all inputs and before the power amplifier (loop), e.g. use the Tape 3 Rec/Play connectors. If the equalizer itself has a Tape Play/Rec input/output and switch, the options become even richer. The correct cable connections and switches positions are explained in words and diagrams in the Akai Owners Manual (enclosed in the package). The amplifier can operate two sets of loudspeaker boxes – A and B. The sets can be independently switched on and off from the front panel. The amplifier construction is very solid, with an aluminium front panel, and knobs and handles of massive plastic in satin finish. The power switch and the inputs switchboard are equipped with indicator lights. The output connectors are sturdy color-coded screws (no spring clips), where the loudspeaker cables can be fastened reliably. The amplifier operates with a protective switch-on delay of a few seconds, and has a built-in overload protection. The sound is clean and precise, with bright treble, detailed mid-range, and natural, smooth bass. The amplifier is fully functional, with all controls, indicators and connectors in good working condition. The amplifier is in a very good cosmetic condition – without scratches, dents, peeled or rusted spots, without any odour or discoloration. There is a very minor, hair-thin wear of the black paint along a short stretch of the top rim of the front panel. There is a minor scratch on the back of the top panel (left edge). The spots are shown in close-up on two of the photos. The amplifier has been used carefully, in a smoke-free and pet-free household, at room temperature. The case was thoroughly cleaned inside and out. All switches, selectors and potentiometers were pump-dusted and deoxidized. I am selling the amplifier due to removal to a smaller apartment and downsizing my Hi-Fi system. The set contains: the Akai AM-35 amplifier two professional audio cables, with gold-plated RCA cinch connectors the Owners Manual (in English) the Service Manual (in English) with the amplifier schematic and circuit boards layout. The set will be packed in a sturdy cardboard box, protected with lots of elastic pads, styrofoam and soft wrapping. I will ship with BPost, DPD or GLS, in accordance with buyers choice. Once You buy the set, send me a message in eBay, of which shipping option You prefer. I will send You an eBay-invoice with the correct shipping cost, and You will pay on that invoice. Thank You!
