Yamaha CS80

Hi Juergen, Richard.. 

Happy new guys.. I was under the impression that a 110V CS80 couldnt be 
converted to 240V. I had my CS80 restored by Kent (KSR) and thats what he 
told me. 

Btw, does anyone have any hum on their chorus/ tremolo section when engaged? 
Mine hums real bad and im sure its not supposed to be like that! 

Congrats on the CS80 btw Juergen, what a nice christmas present ehh! ;)
Have fun! 

All the best,
Rob.
