Default Re: Philips FR-740 working but no audio output

7309 could be bad cap 2365 could be bad, something is killing that voltage. all the other voltages seem to be close except this one. and it is the "AMP ON/OFF CIRCUIT"

I checked the schematic for a FR975, which is similar (more power) and that same circuit shows a negative voltage on transistor 7309 that is more than the 1.44 volts you measure there. so I assume the schematic is correct
