In 1958, I built a C E 20A.  I learned so much about phasing, RF, control 
circuits, etc from this great project.  I kept it all these years - not 
using it for at least two decades or more but I sent it to Nick Tusa who 
completely restored this baby.

I also sent my 458 VFO and the 600L.  Nick did a marvelous job, of course 
and upon its return I began using it more and more.  After a good 30 to 45 
minute warm up, I have very little drift - oh I recheck it about every 30 
minutes or so.....not a big deal.  The combination is fantastic.  The 
phasing generator sounds wonderful with my new PR 781 microphone.  Many 
times stations will not believe I am on a 1958 kit!  Of course many were not 
in the hobby when Wes Schum was king - and you thought it was Art Collins. 
NOPE....it was Wes.

Bottom line.  Get that baby all cleaned up, retubed, aligned and ENJOY! 
Join us on the Sunday afternoon Vintage SSB net  14.292.  You will hear 
several C.E. products.

If you haven't figured it out, I STILL have that great passion for this 
hobby and the C.E. 20A that began in 1950's !  Keep the legacy of Wes Schum 
alive.
