【Overview】 ・This item is a repaired and restored piece of junk from approximately 50 years ago. Although all functions have been confirmed to operate normally, 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. We sincerely hope that those who appreciate the value of a repaired item, rather than such individuals, will consider purchasing this item. 【Product Description】 Product: Stereo Cassette Deck Manufacturer: Sony Model No.: TC-K5 Release Date: Around 1977 Price: 59,800 yen 【Appearance】 ・The front panel and function keys are clean, with almost no noticeable scratches. There is a thin dent about 1cm in diameter on the rear right side of the casing, and a very slight rust was found, so it has been repainted. Considering its age, it is considered to be in near-mint condition. 【Repairs and Adjustments】 ・Complete disassembly, cleaning, and repair of the front and rear drive sections, and application of lubricant. ・Complete disassembly, cleaning, and repair of the head block. ・Cleaning of the recording and playback volume controls. ・Replacement of capstan, reel, and counter belts. ・Repair of playback, auto-shutoff, fast forward, and rewind mechanisms. ・Repair of the first and intermediate amplification circuits. ・Repair of the cassette folder opening/closing mechanism. ・DC servo motor speed adjustment. ・Playback, recording, and VU meter sensitivity adjustment. ・Playback/record head azimuth adjustment, demagnetization, and cleaning. ・Cleaning of pinch roller and capstan. 【Operation Check】 ・All functions, including recording, playback, pause, fast forward, rewind, Dolby circuit, timer standby, and memory, have been confirmed to operate. 【Sound Quality Check】 ・Wow and flutter is 0.09%, which is very good. As far as listening to commercially available music tapes, I believe it produces good sound suitable for music appreciation (playback may be impossible depending on the tape, such as overseas-made or old tapes). 【Included 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. ・Playback speed (pitch) requires opening the casing, but fine adjustment is possible with the semi-fixed resistor in the motor control circuit. 【Reference】 https://audio-heritage.jp/SONY-ESPRIT/player/tc-k5.html
