Crumar Musical Instruments User Group.

Hi Niels,

Thanks for your tips and sorry for the late response. Somehow I don't get the 
messages of this group in my mailbox.

Anyway... I already figured that it would be something like a CEM3328 not 
working and indeed... 2 out of 6 are really gone :(

Regarding the soldering tip... I think I'll do just that in one of my spare 
weekends. After having read your msg I inspected the board and indeed 
some of the solderings aren't too good.

Thanks again... 

Groeten, ook uit Nederland (Utrecht) ;)

Artur
