Does your deck retain its alignment in both directions? That's the problem with auto-reverse - It has a tendency to knock itself out of alignment, have intermittent alignment or be aligned in one direction only.I dig decks with adjustable bias. Makes all the difference in the world. Auto-bias is possible, since the idea is to set bias where response is right. So perhaps the deck senses the output of the playback head and adjusts bias for best response. Do recordings sound good with various tapes?
