Last year when I had to perform that on my A600, I wasn't brave enough 
to use ceramics just right away. I used SMD tantalums (with the only 
exception of the two audio coupler caps... those were replaced with 
standard so-said-longlife |-) alu electrolytics). Even the tantalums are 
different enough in nature so that there is a possibility of problems, 
but I thought they were a good compromise. (They at least don't exhibit 
an electromechanic modulation factor |-) ).

Best regards,
