Noob question, Slow Loris

[woolie]

I building the Slow Loris as per the instructions.  I had assumed that C3 (30pF) was a ceramic cap based on the value.  But for the life of me I can't find a 30pF Ceramic Cap, 33pF yes, but not 30.

Any guidance would be appreciated.

A 33pF is fine. I have some 30 pF caps, so they are available, but not really common it seems. You could also use a Silver Mica if you can find one of them in 30pF.

Go with Jacob's suggestion, but if your still hunting...

Tayda has a good selection of general parts pretty cheap.  

The funny thing with most ceramics is that they tend to have a 20%+/- tolerance anyway, so in theory they could be labelled 30pF but  actually be anywhere from 24-36pF

If you live in the states this is a great supplier... $10.00 minimum order though but free shipping on everything and ships in 4 days. I have ordered from them many times and I always get the stuff in 4 days and sometimes 3. They have 27pF and 33pF but don't seem to have any 30's... They look like a spin off from Tayda..?

Your are so correct. Most of the ceramics I've tested to use tend to be in the 15-20% range of their tolerance. Makes it hard when you need such an exact value...
