Defect of Mayak 230x 240x series tape recorders
When repairing Mayak 230-240 series tape recorders, the feed or take-up side unit often turns out to be faulty. This defect manifests itself in incomplete tape rewinding, and the tape also doesn't move smoothly during playback.
One of the causes of poor feed/take-up unit performance is cracks in the reel housing. The video shows how to fix this defect.
