【Overview】 ・This item is a repair and restoration of a junk item from approximately 50 years ago. Although the normal operation of all functions has been repeatedly confirmed, 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. We kindly request no claims and no returns. 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 No.: TC-K5 Release Date: Around 1977 Price: 59,800 yen 【Appearance】 ・The front panel is clean and shows no scratches. There are no dents or scratches on the body, but very slight rust was found, so it has been repainted. Considering its age, I think it is in excellent condition. 【Repairs and Adjustments】 ・Complete disassembly, cleaning, and repair of the front and rear drive sections, and reapplication 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 shut-off, fast forward, and rewind mechanisms. ・Repair of the power supply circuit, headphone output circuit, recording circuit, and VU meter circuit. ・Adjustment of the DC servo motor speed. ・Adjustment of playback, recording, and VU meter sensitivity. ・Adjustment of the record/playback head azimuth, demagnetization, and cleaning. ・Cleaning of the pinch roller and capstan. 【Operation Check】 ・All functions, including recording, playback, pause, fast forward, rewind, Dolby circuit, timer standby, and memory function, have been confirmed to be working. 【Sound Quality Check】 ・Wow and flutter is an excellent 0.10%. As far as listening to commercially available music tapes is concerned, I think it sounds good enough for music appreciation as a cassette deck that is over 45 years old. (Playback may not be possible depending on the storage condition of overseas tapes or old tapes.) 【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 of the FG servo motor control circuit, although it requires opening the chassis.
