Exit, by modifying the AM pass regulator circuit would simply upgrading the Voltage regulator at Q55 be sufficient? I did change it from a 2SB827 to a 817 and also upgraded Q54 from the stock 1869 to a 2SA1012-0. It was my understanding these mods would beef up the ability of the radio to handle more voltage while staying stable and also allowing much better modulation.
