SONY TC-U4 Cassette Deck - Serviced, Fully Functional, Beautiful Condition [Overview] ・This is a restored item, repaired from a roughly 50-year-old piece of junk. While all functions have been repeatedly confirmed to work correctly, it is a very old device, so it is being sold as a junk item. Due to the recent increase in return scams, we do not accept returns. However, there are occasionally people who make excessively detailed complaints and demand a return. Please refrain from purchasing if you cannot abide by the "no claims, no returns" policy. [Product Description] Product: Stereo Cassette Deck Manufacturer: Sony SONY Model No.: TC-U4 Release Date: 1978 Price: 52,800 yen [Appearance] ・While there are slight traces of rust on the VU meter frames on both the front panel and the chassis, they are barely noticeable. There are no scratches or dents, so it is in beautiful condition considering its age. [Repairs and Adjustments] ・Complete disassembly and repair of the front and rear drive sections ・Complete disassembly and repair of the head block ・Replacement of capstan, playback, and counter belts ・Repair of power supply circuit, amplification circuit, and recording mute circuit ・Repair of auto-shutoff mechanism ・Motor speed adjustment ・Playback level, recording sensitivity, VU meter sensitivity, and head azimuth adjustment ・Cleaning of the record/playback head, pinch roller, and capstan [Operation Confirmation] ・All functions have been confirmed to work, including recording, playback, pause, fast forward, rewind, recording mute, timer standby function, SWS, and pan pot function. ・When the power is turned on, it takes a few seconds for the muting circuit to be released until the circuit stabilizes, but after that, it operates normally. [Sound Quality Confirmation] ・As far as listening to commercially available music tapes, it sounds good enough for music appreciation as a cassette deck that is about 50 years old (recording and playback may be poor depending on the tape's storage condition). [Accessories] ・One test tape used for recording, playback operation confirmation, 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, but it requires opening the chassis.
