Hi welcome back!

Hope you got some sleep...

Please, go over the last post I sent - about the Mic wiring.

Than while you can still do simple checks, got an external speaker? (Well you did check PA I presume you used it) so check receive audio QUALITY thru the external SP jack as well - does the tone change, is there any extra distortion - or does it sound like the internal speaker - not like the PA side of the mic. - then you have fixed the audio chip side, but the low power as well as low audio - may be from what we talked about earlier.

Final, Driver and Pre-amp are one issue...

Mic amp and mic gain (Dynamike) are another - so do that Pin 1 to 2 resistance check on the Mic Jack on the radio. Turn the Dynamike control too - for if the short got into the radio - it starts here and the next parts in line are TR 14 too - so again review the previous posts and look at TR14 and Dynamike for now...

Then check PA again. Get it to work right then we'll check the Final and Driver
