My apologies Edward. In the light of comments made by me earlier, I have edited my post.

Edward, these recorders do use dedicated chipsets, the only difference in the speed is the diving down of the oscillator frequency which if memory serves me correctly is done within the TDA1000.

Otherwise the circuits are the same.

These are hellishly complex machines to work on, the chips are as rare as hens teeth, so great care must be taken not to cause damage to them.
