Sadelta Echo Master Plus Frankenstein Project (needs pics and schamatic)

[WINKDOGG]

Hey guys as the title says , I have a Echo Master Plus I got in a grab box of stuff at a swap . From what I can tell it has had a "new cord" a "new mic element" and the battery connector has been ripped out and re-soldered in what appears to be a few different places . I have a volume and an echo slider with a roger beep on off switch and a single meter to help identify the right schematic . I have found a few schematics that wont match up with my board and I cant find anything with the right wire colors I would like a little help getting her back together and talking right . The Mic works but its intermittent at best with lots of squeal, I would like to put a new longer cord on it a nice new battery connector and a new mic element .

You guys have not let me down yet with a single problem or project in my shack and here we go again !

Thanks so much , Brian

The Extra wires with the white connector is mine I run 2 cell Lipos in my power mics not 9volts . Im also a RC Airplane guy so its all about lithium batts now(I have tons of them and they charge in 7 mins and last a year lol) ! 2 Cells fully charged is 8.4 volts so I have had great luck replacing my 9volts and my 7volts in my power mics !
