MOTM

The parts list says 10n (yellow box) for C4, but mine came with a 100n.

I also noticed the AVX 10n on Mouser is obsolete... I'm guessing the 100n is a substitute, 
correct?

Thanks in advance,

Cecil

cecil Without knowing the answer to your question, I would guess that the AVX 10n has been replaced by an RoHS compliant part number.  Did you contact Mouser?

I haven't physically checked my my 800's, but my documentation says
that it is 10N on both the schematic and the parts list.  The only
100nf caps in the kit are the 0.1mfd ceramic axial bypass caps, but
those aren't yellow boxes.

Sorry, I can't tell you what C4 does since the 555 isn't being used
as a timer.  Pin 5 is the "control voltage" which is generally pretty
useless (it goes to the  the 2/3 V+ reference  for the upper
comparator).  I've seen plenty of perfectly functioning circuits
where it was left unconnected, but according to the data sheet it
should be connected to ground with a small cap.  I always used the
same ceramic bypass caps that MOTM uses for the power supplies on IC's.
I'm no EE, but I'm thinking a multilayer box cap of the same value
would work just as well -- 100nf, 0.1mfd, and 104 all mean the same
thing.

Same here. I contacted Paul off list, and he said to just use it. The  
exact value is not critical as it is used more as a decoupling cap. I  
finished and tested the 800 and it works fine.
