Okay, the echo board is a "no brainer". On the solder side back just above the external speaker/PA jacks there is a resistor, that is the "TalkBack" mod, I usually added a "spst micro switch" to turn it on/off. I see the final was replaced, could be a IRF520 or a 13N10 mosfet mod, not sure which. Other than those couple things that is all I see.

Yes I know the "TalkBack" can get annoying. Just lift one of the resistor's leads and add the switch there, I would drill a hole in the back for the switch.
