Hi Mal.

What valve are you using? I am currently building a TX with a 6293 Beam Tetrode in the PA. the building of the two power units has slowed the construction down with the inter-linking control cables etc. The PA xformer is 650 – 0 - 650 volts @ 400mA with a bridge rectifier, the valve max anode voltage is 3Kv and anode current 1.5A. I am hoping for Class C, 500 watts output cw on 472kHz (if we ever get the NoV).

 

73.

This is a 137 Class C amp project, but since CW activity  has dropped to virtually NIL I am not rushing to complete.
