[sdiy] Roland D-10 modifications

Hi Byron,

Some questions:

1. How do I calculate how much bigger the caps need to be?
2. When you say better opamps, do you mean only rating-wise or maufacturing
quality-wise for same ratings?
3. How much bigger a power supply do I need (actually, in this respect what
does 'bigger' mean? Can I succeed by using hte same power supply but
tweaking it to enable more juice, like putting in smaller resistors?)
4. What are ferrites? Where would you add them? What do you mean get the
digital clock hash out of the analog chain? Is this related to quatization
and/or zipper noise leaking into the analog outputs?
5. Since I'm a beginner, does it seem by my questions that these mods are
beyond my capacity (:OP)

I'd like to do it all myself.

Regards,

Yash.
