So i finally get lucky and find a JVC PC-550 for $80 and jumped at it, now when i play the tape deck it plays for about 1 minute then shut's off! I assume this is a belt slipping as the auto reverse goes crazy too. When i plug into aux to play cd i get strong clean sound on left channel but crackling and weak on right channel? So what do you guys think it is that's causing the weak channel maybe loose solder? I hope that i can save this box because i have wanted one since i was 14.
