I was planning on adding a 3 position toggle to my 800s, allowing
for three caps to be selected. The middle range would use the
3.3uf. I was going to use a 10uf for the long range. I hadn't
selected a cap for the short range yet. I was thinking about a 1uf,
but I may go a little smaller depending on how fast I want to get.
I will probably get some stooge panels made for my 800s as I am
thinking of adding some other mods as well. I'm playing with a
design for a voltage controlled trigger/gate delay and also with the
idea of enabling the 800 to retrigger itself so that it would act as
sort of a LFO. I have not decided how much of this to incorporate
into a modified 800. I may just make stand alone addons.
BTW, I was planning on replacing C9 with the smallest cap and then
adding the other caps in parallel when the toggle is switched. That
way I could use a three position center off toggle, but I'm unsure
whether this will create a leakage problem.
