Perhaps we are barking up the wrong tree here too. For example, in the 3600 chassis a 1N4001 diode and a 100 ohm/quarter watt resistor in parallel with C189 are used to compress the negative peak in the AM Regulator circuit. Not in the audio circuit, as was done in the 8719 chassis. If the audio circuit of the 8719 has the negative compression added there, it will also affect SSB audio too since it shares the same IC. We sure don't want that either, since ideally we just want to affect AM modulation. That would just put our nuts in a bind if we did it in the audio circuit.
