I can't hear anything when I play it back after recording. I can hear it if I put it into my stereo cassette player.
Mine also would not play back on any of the channels but would record. The problem was on the lower board, capacitors C105, C205, C305 and C405, all are 220uF, rated at 10V - on a 9V machine! All four went leaky, which meant that the op-amps each were connected to got a bias which drove the output to 8.5V and no output.
I replaced all four capacitors with new ones rated at 25V and it works again!
2 years before I selled this Portastudio. No playback, but I could record and play on another tapedeck. Than 2 years was gone, and now I had 2 free hours for search and repair this failure. I changed these capacitors on the lower board, and - as if by a miracle - playback function works! Thanks c_k_denyer, thanks god that I found this website!

Thanks a lot! This repair worked for my tascam porta 02 mkII as well. The output of my opamps were also reading about 8.5V. The capacitors had different reference numbers (sorry forgot to write them down) but they were also 220uF and only rated 10V. It seemed only a couple of mine were leaky (one showed less than a volt across it) but replacing all of them definitely didn't hurt.
Just curious, were the capacitors visibly leaky before you replaced them? I'm having the same playback issue but my capactiors don't look shot.
