Many thank to WQ8U, N5AIT,W8KGI, AA4RW for promoting CX over the years. Its a great event and to quote the CX web site:
     "The CX is a no-pressure contest celebrating the older commercial and homebrew equipment that was the pride and joy of ham shacks many decades ago. The object is to encourage restoration, operation and enjoyment of this older "Classic" equipment".

 K2AW diode bricks in the ART-13 and GO-9 HV supply,
they take a licken and keep on ticken.

      Power set on Medium.
   
 

Safety first. I Covered the power supplies with the milk carton during the CX. Power supplies will be installed in the center GO-9 Rectifier cabinet after the test phase has been completed. Don't spill the coffee.
