I have two double auto-reverse decks made by Pioneer and Technics.
None have pad-lifters. They also do not have azimuth adjusters. The
irritation with these decks is that can I set up two cassettes to play
in sequence and cap. the output with Audacity. However whilst the side
1s play OK, the side 2s are dull and muffled. I then find that the
heads are clogged up and need cleaning.

So I have a Nak. with pad-lifter and all is well - it plays both of
the cassettes sides quite clearly. BUT its labour intensive requiring
each side of one cassette to be played at a time with manual turnover.
At least Audacity can continue recording throughout.

My conclusion is that if cassettes are a tad oldish they will shed and
clog the heads - caused by the pressure pads. Its a pity the pressure
pads can't be simply removed for non-pad-lifter auto-reverse decks.

BTW I'm only digitising folk music programmes likely aired on AM, or
radio plays. So I'm not too bothered about azimuth adjustments.

P.S. I've heard that folks use PTFE spray (in micro quanitities) to
lubricate the heads and tape path. Would this stop the tape shedding?
