Dubbing from cassette: low quality

Hi!



I have a Technics RS-X40W cassette deck as part of a system (Technics 315-series). Now, I recently started using this again to make my own mixtapes and to record from radio and I was quite positively surprised by the sound quality. I tested recording from a cd to cassette, then did some A/B-testing, switching back and forth between the cd player and the cassette deck, playing the same track - and I had difficulties hearing any differences (except for a bit more noise from the cassette; this was without the Dolby NR).



This deck is a double cassette deck but only one tape can be used for recording, so I use tape 1 for my playback and tape 2 for my recording. As I mentioned the recordings sound great but there are however some problems with tape 2:



First of all, when dubbing from tape 1 to tape 2 there is a large step down in sound quality where I can hear clear differences between the original tape recording and the new one. I figure this can't be the expected behaviour since when using tape 2 to record from any other source (radio, vinyl, cd) there isn't any significant loss of quality, and neither is it when playing back from tape 1.



Second, playback from tape 1 is supposed to work according to the manual, but often there is either an annoying noise (kind of like what you hear when plugging a headphone cable in and out or when touching a condenser microphone while recording) or absence of one channel (left or right).



I would really appreciate some advice on how to best tackle this problem and if there's anything I could try and fix on my own or if need to have it looked at by a professional.



I probably should add that I don't think that there's a problem with the heads, since I have cleaned them properly using cotton swabs and isopropyl alcohol (99,5%) as according to repairfaq.org. Of course, it's possible there's a problem with the playhead of tape 2, one that isn't fixed by cleaning.



I'm very curious to see what others might say about this matter - if I'll be able come close to a diagnose or not.



Thanks in advance!
