Re: Uher Royal Stereo 784
It is possible to control the speed (downwards) on a motor that has a run capacitor by connecting a rheostat across the capacitor terminals and connecting the supply wire to the wiper of the rheostat but once the wiper reaches just beyond the mid point of the rheostat the motor will start to run backwards. I did this on some older Grundig recorders in my (much) younger days.
