US Signal Corps Power Generator GN-51-B

[Jim Price]

Picked up one of these at the show last weekend for $25. Figured that I'd have that much fun tinkering with it! Started on it today and found that a manual would be helpful. Tried all sorts of sites to no avail. Does anyone have any suggestions as to where I might find one? BTW, the selenium rectifier on it looks a bit sick; any ideas on how/what to replace it?

Regards,
Jim
