feature? - Nearly 40 years ago, when the BCL was popular at the time, it competed with the Mitsubishi Gegum series and Matsushitas Cougar series for performance. The 5950 was released with the catchphrases A sky explorer with a cassette attached to the sky sensor and Aiming at the world, recording the world. As its name suggests, the ICF-5900 (Skysensor 5900, hereafter referred to as 5900) was integrated with a cassette recorder, making it a large radio cassette for its time. At the time, a tape recorder that could record broadcast content was the most desired item for BCL fans, but even the cheapest tape recorders in the mid-70s were priced at 10,000 yen or more, so it was not easy to buy. . Since it was attached to the 5900, which was competing for popularity on BCL radio, many BCL fans at the time seemed to have sighed while looking at the catalog. ?name?

[Operation/reception status] ?Radio FM/AM/SW reception operation confirmed, sound quality is good. MW (medium wave = NHK 1st, 2nd, TBS, Nippon Cultural Broadcasting, etc. major AM stations), Tokyo 23 wards in the evening time zone, I was able to receive Sapporo Broadcasting and Kagoshima Broadcasting clearly. SW (short wave broadcasting), We have confirmed reception of FM (major FM stations such as NHK, J-WAVE, FM-TOKYO). ?Energization reaction: Both batteries and power cords are OK ?Each button/dial reaction: OK ?Antenna: It can shrink smoothly with less damage and distortion. ?Battery BOX: No trace of rust/liquid leakage *The reception status varies depending on the reception location and environment. You can use it immediately, so please feel free to purchase it. [Repair and adjustment details] 1: disassembly and cleaning The main body has been disassembled and cleaned with a cleaner. The cleaning of the base, the volume, and the band changeover switch are handled by external cleaning in consideration of the durability of the pattern, and the function is restored. The variable condenser is cleaned to remove static electricity noise during FM reception. 2: Improved operability The moving parts are greased, so operability is improved. Metal parts (E-ring, VR nut, heat sink, shield plate) are anti-rust treated, Since the moving part (dial light switch) is attached with grease, it works well. The rod antenna is lubricated after cleaning the inside of the rod with parts cleaner, so it expands and contracts smoothly. There is a gentle sleigh. The wiring around the battery box and the wiring from the board have been partially repaired. 3: bug fix We have fixed poor contact and gurgling noise due to aged deterioration. You can use it without stress. 4: Calibrating each band Scale adjustment and tracking (sensitivity adjustment) were performed for AM, FM, and SW. 5: Replace with LED light We have replaced the light part with an LED light so that you can use it more comfortably. Dont worry about using it in the dark. 6: FM coverage The upper limit of FM broadcasting is set to 93MHz, and there is a gap between the displayed frequency and the actual frequency. The discrepancy between the dial and the actual frequency is also within a satisfactory level. You can enjoy high-quality sound. 6: belt replacement Since the rubber belt of the cassette was stretched, it was replaced with a new one. ? Cassette part ? Play, record, stop, fast forward, rewind, and pause basic operations OK. ? Line (external input) ? External input confirmation OK. Ideal for sound output from portable devices such as smartphones. It is popular for its stylish 80s boom box. It is clean and in good condition for its age. ?Belt has been replaced and works smoothly. Currently, it works smoothly and the sound quality is good, but you can enjoy it with high sound quality. Since it is a home appliance that is more than 40 years old, I think that the head, gears, electronic parts, etc. will deteriorate over time and will not reach the original performance of a new product.
