It fits on a 190, so that sounds like it would work.

I was thinking of building three versions (I have one 800 built, two kits
arrived last week, and two more are on backorder) making three stock,
one extra fast, and one extra slow. Since I am also adding Moe's LED
mod, my plan is to use three different colors to tell them apart.
I'm thinking of keeping 3.3uF as the stock value (even though Paul S.
says 6M8 is "ideal"), using 1uF for snappy, and 22uF for extra long
sweeps and fades.
Then again I'm just guessing. Based on reported results, 3M3 is 14
seconds and 10M is 25 seconds. So I'm thinking 1M would be be a
maximum of about 7 seconds, (which is still pretty long) and 22M
would be about 35 seconds.

Imho, stand-alone addons would be more flexible and less invasive.

How would that create a leakage problem?? Have you found source and
part number for low-leakage non-polar radial caps?? So far it is
between the Panasonic SU and the Xicon NPRL. Any idea which part
the 800 uses for 3.3uf?? I can't tell from the markings.

Doh!! That should be Mouser instead of Digikey. It's on page 265 of
Mouser catlaog 612. Digikey lists the Panasonic SU.
