Need help
Fitting metal gears.
Made a mess of stripping the wires for the connectors,
pulled out two wires from the circuit board


I did resolder and could get forward L and R but no reverse
It seams I have broken the thin plates that run in the board

Its one of those old ones that you cant get any more ,
its a TX13 no smoker on sound, If I cant get this board
can I use the TX14 board, if I can what are the problems.
My soldering skills are poor and my solderer is out of the ark.
