Emax

Mike, Yeah it was soldered, and quite a fiddly bit for a novice like  
me to tackle. My Emax's life now rests on finding someone skillful  
enough to make good my handy work. As I couldn't even find anyone to  
to replace to power supply recently, I fear the worst. Anybody out  
there got a dead Emax I (rack) with a good button board?

Cheers,
Alan
