Mic preamp question

Brian Mury-3
I have a few questions about the mic preamp on the Elecraft website.

What type of capacitors should I use?

I assume the .0047 caps are .0047 uF (aka 4.7 nF)?

I'm thinking about building this onto a small board with a header that
will plug onto the mic config header inside the K2. Will this affect the
quality of RTTY/PSK31/etc signals transmitted through the mic connector?
Am I better off building this externally?
