【Overview】 ・Wow and flutter is 0.07%, recommended for those who prioritize playback over appearance. ・This item is a repaired and restored junk item from approximately 45 years ago. Although all functions have been repeatedly confirmed to operate normally, it is being sold as a junk item due to its age. Due to the recent increase in return scams, we are very reluctantly unable to accept returns as a general rule. No claims and no returns are accepted. As an exception, we will provide free repair services only if you cover the round-trip shipping costs. 【Product Description】 Product: Stereo Cassette Deck Manufacturer: Sony Model Number: TC-K61 Price: ¥59,800 【Appearance】 ・The front panel is very clean. There are very slight rust and dents on some parts of the chassis, so the rust has been removed and repainted. Considering its age, I think it's in relatively good condition. 【Repairs and Adjustments】 ・Complete disassembly, cleaning, and lubrication of the front, rear, and head block of the drive unit. ・Recording volume, ultrasonic cleaning with ethanol. ・Capstan and reel drive belt replacement. ・Fast forward and rewind mechanism repair. ・Capstan motor and reel motor drive circuit repair. ・Playback equalizer amplifier repair. ・Output op-amp replacement. ・Record/playback head azimuth adjustment, demagnetization, and cleaning. ・Pinch roller and capstan cleaning. ・Servo motor speed adjustment. ・Playback level, recording sensitivity, and LED peak meter sensitivity adjustment. 【Operation Check】 ・All functions, including recording, playback, pause, fast forward, rewind, timer, and memory functions, have been confirmed to work. 【Sound Quality Check】 ・As far as listening to commercially available music tapes, I believe it produces sound quality that is sufficient for enjoying music as a cassette deck that is approximately 45 years old (wow and flutter is 0.07%, which is extremely good). (Playback may not be possible depending on the storage condition of the tape, such as overseas-made or old tapes.) I especially recommend this to those who prioritize recording and playback sound quality over appearance. 【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) can be finely adjusted with the semi-fixed resistor in the capstan motor control circuit, although it requires opening the chassis.
