For whatever it’s worth, I have photos of a 20206 near the bottom of this page.

Photos are probably taken from an eBay listing in 2011. 

No manual, though, sorry.

Does anyone have documentation for the CLG-20206 115VAC power supply for the TBY series of transceivers?   Just a schematic would be very helpful.  We are in the process of restoration for a museum working display.
