I picked up a really cool under dash cassette deck at Goodwill today. It's a Teac AC-9 from 1972.

I opened it up, replace the belt and it actually plays cassettes hooked up to a 12V desk top power supply via the red and black wires. The remaining wires are;
Yellow
Orange
Blue
White

It has a balance on it so it should be stereo. I would imagine the remaining 4 wires are positive and ground for 2 channels, however, I can't find a wiring diagram online that tells me what's what.


No longer taking $h!t from anyone!
