新品?昭和52年パイオニア製カーステレオの動作チェックとメンテナンスをしてみた
I did some maintenance and checks on a new Pioneer KP-450 car audio, released in 1977. I wonder if it was dead stock from a store? It was a 42-year-old car stereo. The radio frequency display is nostalgic. The amplifier output is 8W x 2ch. I couldn't find a cassette tape in good condition, so the cassette deck test was left half-finished. ・Replaced rubber belt https://amzn.to/3cz5WcR Amazon link is an Amazon.co.jp Associate ・Tool information is posted on Twitter (there is also a Q&A corner) / diy20414383 #Pioneer #CarStereo #Maintenance #Repair
