Greetings again. Any Icom experts out there? I am wondering if the PLL board of the Icom IC-751 and IC-751A and IC-761 are identical? I know they seem identical in "appearance", but am aware that components could be totally different. Does anyone know the answer to that question? I am trying to repair the PLL board of my deaf and mute 751, and so far have not been able to get it to do anything (I don't find any RF signals on the PLL board anywhere with RF voltmeter or frequency counter, not even the calibrator "marker" signal). Am wondering about replacing the whole board with one I have found online. I still need to check voltages on it too.
Thank you for your time and input.
