    But would PA work - try PA.

    IF no audio suspect Audio amp chip and support parts...

    Also check GNF board, and J25 connector make sure all wires to those connectors are seated...

    There are two variants of the board, one with the TA7222ap and TDA2003 chip (5 pin).

    The GNF "noise filter" board can interfere with audio - but would TX ok.

    Else get to the link Robb supplied - and remember to look for the chip design and the layout is update on the TDA2003 5-pin chip.

    Have fun...

    Then that means if PA has audio - Audio Amp chip works. Now - work on the mods part - the speaker? Can't help but wonder...

    More than likely a audio mod in there that's failing.

    If my hunch is right they use MOSFET for switching power loads - so to have one fail or the speaker quit working - shows that the original designs' been modified - to what? I don't have much to go on, just your words...
