Sony TC-KA1ESA ES Series Vintage Stereo Cassette Deck - AS-IS / PARTS REPAIR
Vintage item sold in as-is condition, for parts or repair only.
Known Issues:
Deck will damage tape near the beginning of a cassette after a full rewind. During testing, tapes played normally when started from the middle of the cassette. Cause has not been determined and repair is recommended before regular use.
During calibration testing, the bias adjustment must be turned fully counterclockwise to achieve balanced meter readings. This behavior is not considered normal and may indicate an underlying calibration or circuit issue.
No further troubleshooting, diagnostics, or repairs have been performed regarding these issues.
There is no guarantee of functionality beyond what is described here.
