【Overview】 ・This item is a restored and repaired piece of non-functional equipment from approximately 45 years ago. While all functions have been confirmed to operate correctly, it is being sold as a junk item due to its age. Occasionally, there are people who complain about issues unrelated to basic functionality, such as excessive noise on one side, slow folder opening, or dissatisfaction with the lighting brightness, and attempt to return the item. I sincerely hope that those who appreciate the value of a repaired item, rather than those types of individuals, will consider purchasing this. 【Product Description】 Product: Stereo Cassette Deck Manufacturer: Technics, Matsushita Electric Industrial Model No.: RS-M13 Release Date: Around 1981 Price: 32,800 yen 【Appearance】 ・Both the chassis and front panel are clean and free of dents, but there are signs of use on the function keys. Overall, I believe it is in good condition considering its age. 【Repairs and Adjustments】 ・Disassembled and cleaned most of the front and rear drive units, applied lubricant. ・Cleaned the recording volume. ・Repaired the cassette loading mechanism. ・Repaired the muting circuit. ・Fine-tuned the motor speed. ・Adjusted the playback and recording output levels. ・Adjusted, demagnetized, and cleaned the playback/recording head azimuth. ・Cleaned the pinch roller and capstan. 【Operation Check】 ・All functions, including recording, playback, pause, fast forward, rewind, and timer recording/playback, have been confirmed to work. ・Technics decks have durable belts, and most models can be used for approximately 45 years without replacement. 【Sound Quality Check】 ・Wow and flutter is less than 0.08%, which is excellent. As far as listening to commercially available music tapes is concerned, I believe it produces good sound that is suitable for music appreciation as a cassette deck that is approximately 45 years old. (Some tapes may not be able to record or play back depending on their condition.) ・Equipped with a 4-position tape selector with a metal position. 【Accessories】 ・One test tape used for recording, playback operation check, and adjustment. 【Important Notes】 ・Please use it for about 1-2 hours a day, as the resin parts have deteriorated over time and may cause malfunctions. ・The playback speed (pitch) can be finely adjusted with the semi-fixed resistor in the motor control circuit, although it requires opening the chassis. 【Reference】 https://audio-heritage.jp/TECHNICS/player/rs-m13.html
