20A Rack Mount
Number 2






This CE20A rack mount model was a gift, from WC3E, who I specifically told, NOT to bring anything to me
because I have zip, nada, none, as in NO ROOM for anymore equipment. Well He and Mike WN3B came up on
a rainy weekend for a visit and Breakfast, and conversation. I showed them some of the equipment, and also the
crowded situation, and then they were getting ready to leave and Frank said we will leave right after I give you
these things I brought. "These Things" turned out to be two CE-20A chassis in various states and he said, "I figured
you could use some spare parts", so here you go.





What to do, hum well I did have a 20A with a pair of open RF mixer transformers, so I considered that, and also
there was the second "Rack Mount" front panel for the 20A, so why not?

I replaced the transformers, also checked the rest of the circuitry out, put back the original 5U4 rectifier, brought
the plate voltage back to 360 volts and checked all the operational portions of the exciter for proper  operation.


I did some touch-up painting to the front panel, and the cabinet, to give it a good appearance, and this rack mount
CE20A is now being used to drive my Homebrew single 813 RF PA at around 250 watts input.

NOTE:  The cover for the rf plate circuit for the 6AG7s should be in place in the rack mount and desktop model,
otherwise the unit suffers from feedback and microphonics when driving a linear amplifier.
