It had really sprung out of place on the right side, so I am not too optimistic about this.but again, I had nothing to lose by trying. This morning, I decided to try and glue it back together.

How did I get the knobs back on the mode and function switches without breaking them again? I then reinstalled the face plate (after cleaning it up), reinstalled the knobs, and reinstalled the top and bottom covers.Īnd here it is, playing the smooth sounds of Nat King Cole. I polished all of the knobs with Mother's Mag & Aluminum Polish, which really helped them - especially the Tuning and Off-On-Volume knobs, which were really grungy. If it didn't work out, I had already spotted an S-8900A, and I thought I might end up using this 7900A for parts. The seller was very nice and agreed to give me a partial refund. Not only did I have a damaged cabinet, but the mono-stereo mode switch and the function selector switch were both broken - they rotated like potentiometers with no "clicks". Unfortunately, USPS did what it does best to vintage electronics. This was great for me, as I had wished that the S-8900A I had years ago had been an S-7900A so I could have AM as well as FM. Now on a stereo kick, I had been looking for another Sherwood to replace that S-8900A but until recently had not had much luck finding one.įinally, an S-7900A popped up on the auction site. It was roughly ten years old, or nearly so, when I acquired it and I troubleshooted at the component level to fix just what was wrong.įast forward to 2016. In retrospect.I should have replaced both of the 7000 uF electrolytics, not just one. Pioneers of the 1990s were not as good as their 1970s-1980s siblings, but what did I know at the time. Then I did something I now regret.I threw it away and bought a new Pioneer receiver.
I used it for about fifteen years or so until it started blowing fuses again. Replacing diodes, fuse and one of the big 7000 uF power supply electrolytics.I had a working receiver! I took it home and discovered a blown fuse, bad rectifier diodes, and a questionable power supply electrolytic. This FM-only receiver was rated at 60 watts per channel, not bad for a 1974 receiver. Back in the early 1980s, I bought a nonworking Sherwood S-8900A stereo receiver.
