NorCal 40 Parts Info

Greetings to all.

I have (almost) all my parts ready for the arrival of my NorCal
40 Partial Kit. I am posting to point out that Mouser is out of stock
of 2.2 uF 50v non-polar electrolytic caps. They told me maybe sometime
in October. The good news is Radio Shack stocks them. The bad news is
they cost 4 times as much at about $1 each. Oh well, we only need 4 of them.

I also thought I would mention that in the parts list Doug so
conciderately posted, I found what I think is a tiny nit. The rubber
feet are listed as being from Digi-Key. I could only find the matching
part number in the Mouser catalog.

On a related note: What are some ways to "match" the crystals for the
filter? I read the pertinent parts of SS Design and the W1FB Design
Notebook. The crystal characterizer instrument looks neat, but I'm
sure not going to build one in the near future. At minimum I thought
I would throw together a little oscillator and match them for
frequency with my counter. As for the equivalent series resistance and
bandwidth, I don't think I have the appropriate gear here for that.
Suggestions?

Thanks!
