[Elecraft] Need help with K2 capacitor

Wed Nov 12 11:25:11 2003

Thanks to all who replied on this.  As one fellow (probably my age) pointed
out, for many decades a cap that said 470 on it was a 470 pf cap.  I knew
that was no longer the case, but it simply slipped by me.  Indeed, the newer
K2 manual specifies that this cap will say 47 or 470.  My older hardcopy
manual says only 47 and that's where I went wrong.  The caps installed are
the correct ones.
