This is a Pioneer cassette deck CT-6. I don't have the equipment to check the sound output, so I've only done a basic check. The basic functions like play, fast forward, and rewind seem to work fine. Other functions are untested, so I'm selling this as junk. Please purchase if you are able to perform maintenance or repairs. Shipping will be in a simple package using recycled cardboard. Due to the size of the item, returns and refunds will not be accepted after arrival. Please understand this beforehand. Thank you.
