The replacement motor is type EG-530AD. They are fairly widely available in the usual places (ebay, aliexpress etc) with prices between £1-£15. Mainly depending on how quickly you want one :-)
Always enjoy seeing something that never made it to the States. 1976-1979 when I was a teenager and wish I could afford a bottom end Pioneer stereo receiver that was pushing $400.00. I draw the line 1980 on....................which I consider Junk.
