Shoot - thanks for trying...


Well, if it is the audio chip - the thing running that low - would be VERY HOT from excessive input and drive out.


I mean - if it was working as an audio amp - because the amp certainly seems to be working - but unless there is some form of failure - you should be able to take an ordinary speaker - and place it right across the output cap to ground - or from this point even a DVM set for continuity look at the speaker built in and try to locate the "ZERO" dead short to it. If the line to the speaker is correct, you'd see only 8Ω on one side to speaker terminals and the other side would be "0" and a BEEP if so equipped.


I've had to do this to find the corrected polarity of the speaker - but then too - I've also seen speaker wiring that has had bad wiring - in this case age.


So if the SQ amp was ok - and PA seems low too - then YES the output seems odd to be as low as it is...


Did you check [USER=1368]@loosecannon[/USER] post on seeing if the relay to the speaker was ok?


This continuity check might help show if the relays contacts are bad.
