Found an old cassette tape lying around, so charged my spare 12V battery and gave the retro Pioneer Lonesome Carboy audio system that's going into my RX-7 a test run. The deck needs a decent head clean, and the speaker I used was rubbish, but there's definitely some potential there.

You may be able to spot some other decks in the background - those ones have broken head motors, so I'll be opening them up and trying to figure a way of tapping into the preamp so I can hook up an auxiliary cable.

This is what happens when you've had a quiet drink on a Wednesday night and can't find anything better to do!
