[GreenKeys] Mystery rectifier

[groupsrichart at gmail.com]

Looks like a homebrew loop power supply. The electrolytic caps are 
probably toast and those selenium rectifiers are really nasty when they 
fail. The only things worth salvaging are the power transformer and the 
wirewound resistor with the sliding tap that was used to set the loop 
current.
