Hey all! After my love affair with the sa80 I decided to keep an eye out for similar models and picked up the Sa75 for £4.20. It arrived this morning and after a quick clean is working nicely. This model does have Ultra Phonic Mode which appears to be locked in position as no obvious difference is clear. Dolby and tape type work fine, radio works fine. The models are essentially the same aside from the digital display and emergency stop feature on the sa80. The only question is what year it was produced. Here’s some pictures, it’s got some light wear on the front
