Ok thanks the ic3 taken care of and it's working so someone must of been in this before for some reason good to go now.On IC4, the MB3756 voltage reg/T-R switch pin 7 is not connected. Circuit doesn't use it. On IC6, the TA7222AP audio power chip, pin 3 is not connected. That pin will mute the audio, but this radio doesn't use that feature of the chip.
IC3 is the AN612 balanced modulator chip. All 7 pins on this one should be connected.
