Bill:
I sent you an e-mail suggesting the external speaker jack could be suspect.
You can short the tounge<sp> and the ground and see if your internal speaker
works. You can proceed from there. If that is the problem it may only need
some cleaning, if not bent.
Best regards,

excessive heating. The series RC on IC audio stages is NOT switched out,
especially when using an external speaker with extra lengths of cable that
provides varying feedback.
Yeah, I looked at the schematic last night, and it has to one of three
things ---
the speaker itself, or the wiring to it, or the head phones or external
speaker
jacks --- the audio line goes through both on the way to the internal
speaker.
Steve made a good point about the speaker bracket... I'll see if it will
"hinge" up as he suggested on the Argonaut II.
