1970s Zenith All-in-one Stereo with record player issues

[Olorin67]

I worked on a number of different changers, most designs had an Achillies heel or common service issue. The BSR units are easier than some, and usually rdont require complete disassembly. There are some changers that you really need to take apart completely to service properly, BSRs are a picnic to work on compared to a Dual, PE, or Webcor. Most designs have a weak point or two. Or develop issues due to aging. The most trouble free ones I've encountered are later ones from panasonic or Sears Silvertone, later units often had more plastic parts that worked without lubrication, less parts to get gummed up with age.
