Nortronics is no longer manufacturing heads, but a meaningful supply of them
in NOS condition is available from JRF magnetics. John French purchased
that inventory about a year ago. By fortuitous circumstance, prior to that
sale I'd purchased what I was told were all of the remaining 8 track repro
heads. My intended use for them is in my AG440W: not to play tape.
However, one could be rather easily installed in a spare 440 head ass'y for
the purpose of playing such tapes. Whatever wear the heads would endure
playing tapes (that of course had been extracted from their housings) would
be virtually nothing was compared to what wire does to them.
JRF is located in Greendell, New Jersey. Their phone #s 1-973-579-5773.
Their fax #'s 1-973--579-6021. They have a website.
