This unit is having difficulties playing audio CD-Rs. Not every CD-R has problems, only some of them and the problem consists in not locking into the tracks. The strange thing is that the CD-Rs are all of the same brand, same manufacturing date and even from the same canister!(TDK 48X, 80min). I opened the unit thinking that perhaps the signal gain need to be slightly adjusted. I found 4 potentiometers called:
- T-OFFSET
- T-GAIN
- E F/BAL
- FREERUN I tried to adjust them with no avail. Any leads? Thank you very much, Gene
