I have a demag cassette from tdk this is simply an oscillator withe a small
button cell and a microswitch behind the coil that pusheds up to the head
when play is pressed. it is designed to tail off slowly.
Not sure what frequency it uses. Could this advert merely be incorrectly
labelled?

I'm sure I'm going to regret this . . . why does the screenshot show
different waveforms?


"We have designed the DM1 with a second demagnetisation cycle at a
different frequency as we find this offers optimal performance. Each
demagnetizing cycle on the DM1 takes approx 10 seconds. "
