I have replaced several push to talk buttons in the last few years, it is simple if you have basic soldering skills.
You may want to borrow a friends mic first and try it and see if that is you problem.
Good luck, it a great radio don't just shelf it.
FT-742A Audio Problem
Just bought a FT-742A with the same problem. Found that the 8 V DC (actually around 6 V on another 742 I have) that feeds the mic was missing. Opened the mic and found there was around 4 V for the key pad and the other mic functions on one of the other pins so I jumped that voltage over to the 8 V line. The lower voltage seems to work ok. You have to follow the color of the mic cord wires to find where they go. The 8 V line is suspose to be on pin 2 looking at the front of the plug in the 742.
Hope this helps.
