Cassette deck head wear


Forgive my question, but how do you estimate the head wear more or less precisely(+/- 10%)? My Nak682ZX sounds no worse than before, but the playback head does not look exactly new? How many hours do they usually last anyway? I use only Metal tapes.Will appreciate your responses.

agree that Dolby C breathes & pumps levels excessively

don't forget to degauss those heads & capstans, even though you're not having to clean very often
