    I found a bench-level repair guy who was willing to look at it, and he thinks it is a MOSFET:

    "found a short across the main power input"
    "having a rough time identifying the exact part number of the MOSFET that's failing"

    So, we'll see where this goes.

    If this goes well, I have a bass amp he can look at, too.

      If you can get a clear picture of the part maybe we can figure out what it is.

        I might have lost this radio to this person. After a few emails, he no longer is replying. Hmmm...

          I got it back and we looked at the part. I posted photos asking for help, here:


          Thanks.

            Me too

            My radio is now just ticking as of yesterday...was listening to a stream and...croak.

            I see several threads involving this issue but I haven't yet seen if anyone has been able to fix the problem. I have to run something else to a shop one of these days and am wondering if there's any point in bringing the Radio along.

              Then, let us know, please.

              The guy I was referred to has quit board repair due to shaking hands.

                I looked at everything I could find, but didn't see anyone reporting success.

                If I can ever get off my behind and get down to the shop (it's *just* inconvenient enough to make me procrastinate) I'll report back.
