Hello! I recently got some B&O equipment that I wanted to fix up and I decided to start on the Beocord 5000.   I cracked it open, cleaned it up a bit and replaced the belts. They seem to be working ok and all modes seem to work without a tape in place, but when I put a tape in, the capstan moves but the take-up reel doesn't move. The only soft part I haven't replaced is the idle tire. Is that likely the culprit or do I have something else I need to hunt down going on?
