[R129 SL] FW: schematic request

[George Simpson]

It should perhaps be mentioned that Jan is, I believe, an electronics 
engineer by profession. The sight of the back of a corroded printed 
circuit board scares most of us sh----ss but, if  you are going to junk 
the board, I would at least follow Jan's advice and have a go at 
cleaning and repairing it - you got nothing to lose and what a sense of 
achievement if you repair it!!!!
