    “Ian,

    Ari is correct, you can substitute the 435Al-1. There will be a small difference in response above maybe 6 kHz with the Al-1 being smoother and a little lower in output.

    I am surprised the magnet shedding would cause no output. It can cause massive buzzing, but there may be something else wrong with the diaphragm.

    Regards,

    Greg”

    Thanks Ian, really appreciate that.. Now to either find some 435AL-1 ... or repair that diaphragm.
    If i thought it wouldn't potentially damage the working diaphragm i have in the other 435AL i'd take it out and test it on the non working one & thereby confirm the magnet is still ok..
    I did note that there is some mention of repairing the diaphragm in this blog so that may be a worthy cause as finding a replacement is far from likely.
