Jess,
You may use any small 4.7 nF cap instead of the SMD if you solder it with
short legs.
I would send you a 4.7SMD by mail ofcourse, but I am afraid it will not be
at your location in time to finish the project before Xmas

You could make a temporary gimmick cap by soldering a short length of
small gauge insulated wire to each pad, and then twisting the wires
together a few turns.

Probably inrush current charging the capacitor(s), I have heard it in other
supplies (astron). You could shock mount the transformer maybe if it bothers
you too much!

Hi guys & girls,
In 2003 approximately I built the Elecraft K2 as a
beginner. Then I
added on the KNB2, KIO2, KSB2, K160RX, KAF2, KAT2 &
KBT2. I have since
added the official mods from the start to A to B
revision changes and the
2nd XFIL modification. This is all I know or can
remember adding.

I operate my K2 on a 48' St. Francis Catamaran (The Quantum Leap) that I

lead and terminate it in a LGP 4:1 Balun and run about 20 feet of RG58 to
the K2. I install it as a sloper from the top of the mast by conne
That 'thudding' is the transformer going "Ugh" during the first half-cycle

My Astrons all do that was well.

I agree with all that, although I remember referring to GHz as gc (as in
2.1 gee-cee for 2.1 GHz).
My profs only knew Hertz as a radio pioneer... not a term... and my
