TRA931X Switching & Fixed Level Audio Amplifier Board

Tone All Messages By This Member #6656 Hi guys, I'm bringing a TRA-931 back from the dead. On my RF board sits a piggyback board which I presume is the Switching & Fixed Level Audio Amplifier Board. This is though, very different to the one shown in the manual. Nothing matches, pin numbers, semiconductor count, semiconductor type etc etc. Mine is marked CD713250, yet the one in the service manual is CD713163. Is there a schematic for the type of board I have? ? ? ? ?
