I have a Pioneer RT-909 that doesnt sound great playing back. sounds sort of like the tracking is going off a bit. Kind of wobbly. I can hear it while recording as well. played a tape I made from my Teac and same thing. I just noticed the pinch roller wheels are out of round. Wonder if thats the cause? will order some new wheels just wanted to get some feedback on this issue. Not at all familiar with this model. Just got it. Thanks!
