Tangling the tape in play mode, and when trying to rewind, it would freeze and turn off. | The tape got tangled because of the "crazy" pulley with the factory grease that turned into glue due to age, clean it well with alcohol or solvent, and lubricate it, as for the locking when rewinding, guide posts completely locked, the rollers did not rotate freely, and the top of the tape was crushed, I replaced it with other posts in good condition, the defect was resolved. | Remove the old grease from the crazy pulley, and lubricate it again with mechanism grease or blue grease. As for the guide posts, tsound is no way around it, you have to replace them with scrap ones in good condition and readjust them. | Trendset |
