- Notes
-
The Bud Radio Codemaster CPO-128 is a code practice oscillator that can be used as a speaker or cpo by selecting "M" (monitor) or "C" (code) on the side of the cabinet.
There are three versions of the Bud CPO-128: CPO-128, CPO-128A and CPO-128B. This version, with the 117L7GT or 117N7GT or 117P7GT tube, red lettering and cross-hatched grill, had one side of the AC line directly connected to the key, creating a safety hazard and was changed to the CPO-128A. The three possibilities of tubes are a combination AF amp and power rect.
