.
- Anmerkung : Optisch passen diese beiden Geräte wie die Faust aufs Auge. Das empfanden die Kunden damals genauso und so wurde der Tuner ein Flop.
.
Der SM83 war für seine Zeit ein toller Verstärker
Alleine die Optik war für damalige Zeiten ganz anders als die Normalität der deutschen Geräte. Weiterhin hatte der SM83 die ganzen Cinch Ein- und Ausgänge und er hatte dazu zusätzlich auch eine DIN Buchse für deutschen Tonbandgeräte.

NOTE SOME OF ITS OUTSTANDING FEATURES : SM83
.
- Hier fingen die Japaner auch schon an mit diesen sogenannten "outstanding" Features. Alles war auf einmal "outständig" = super herausragend. Aber mit den 4 x EL84 war das noch lange nicht herausragend. Soetwas konnte Max Grundig mit dem NF 20 auch, nur halt nicht so "schön".
.
- The heaters of the preamplifier section tubes operate off well-filtered DC, for hum-free and crystal-clear reproduction.
- The output circuits are comprised of two pairs of type 7189A high-power output tubes operating in fixed-bias push-pull circuits, to provide a full 40 watts of stable program power per channel.
- Distortion is exceedingly low, making the SM-83 an ideal unit for the home or for professional applications.
- Each channel is equipped with independent treble and bass tone controls for easy adjustment of tonal quality, to provide the optimum tone matching the listening room.
- An effective low-cut (rumble) filter is provided to eliminate rumble or other low frequency noises, and a high-cut (scratch) filter to eliminate scratch or static, for clean, noise-free reproduction.
- A loudness control that can be switched ON or OFF at will is provided, so that true high fidelity reproduction is provided even at low volume settings. One of the main features in the design is its ease in handling, that enables it to be operated efficiently by anyone. The controls are positioned for efficient operation, while the selector and mode switches are comprised of pointer type knobs', so that the program source being listened to can be discerned even at a distance.
- A jack is provided on the front panel for connecting a stereophonic headphone set for individual listening.
- The SM-83 is designed for maximum versatility. It has the following stereophonic inputs : TAPE HEAD, TAPE AMPLIFIER, MICROPHONE, AUXILIARY, and both MAGNETIC and CRYSTAL/CERAMIC PHONO inputs.
