Braun tg1000 capstan's motor sound in the speakers.

If I disconnect power supply from the capstan motor I hear only typical noise of electronics.

In normal operation with 24V connected running capstan and slowing it down with fingers I hear different pitch of hum in the speakers.

For example going from rewind or FF to play mode I hear loud hum (50Hz?) for couple of seconds before tape starts playing.

It is very annoying and takes away pleasure of listening.
