After replacing all 3 rubber tires from this trusted seller I got a horrible wow and flutter, I haven't replaced the pinch roller yet but it worked fine after replacing the belts and prior to replacing the rubber tires, I may have to put the old tires back on but before I do that any other reason that may cause this problem? I'm really disappointed. With the PCB flipped out, I fiddled with the motor while the tape is playing by pushing it down or lifting it up to no avail. I also would like to point out that W&F worsen when the take up spool is full and sometimes stops and tape gets eaten before it goes to auto stop.
I don't know about yours, but on many players the assembly including the rollers moves when Play is engaged, so the rollers need clearance for that repositioning.
No, these are identical to the original parts. Besides, I did not replace the pinch roller just the idler tires.
What are the W&F figures before/after ? Used these rubber tires and capstan ring for a long time and didn't have problems with it. Is there any visible wobblying of the rubber when running ?
I did not measure the W$F before, but now it's audible, something is wrong but I don't know what it is, I will try to take a video next time with the PCB flipped out.
