I recently got a tascam 244 off of ebay for cheap and replaced the belts and idler tires and pinch roller and cleaned the whole thing out. i started making test recordings on it and had no issues til yesterday. tracks 1 and 2 will record fine with good levels on the vu meters and play back fine. i go to record on track 3 and 4 and when i record the levels look good but on playback the the vu needles barely move and i have to turn up the volume on the track, buss monitor, LR master all the way to hear anything. then as this problem started to happen the same thing started to happen on track 1 with the same recorded signal that had previously been playing back fine. track 2 is still working fine so i thought maybe i would clean the tape heads again and sure enough they were pretty dirty but i still have the playback issue. the tape im using is a brand new type 2 tape audio pro c-60. wondering if anyone else has had a problem like this. this issue happens on both remix and cue with headphones and speakers.
