Jackson 641-A signal generator
#1

I just bought this on eBay. It should be useful aligning FM receivers like the Philco 48-482, which I had to do using the old method outlined in the service instructions, but was not the preferred method.

By the way, does anybody have the manual for it, or know where I can get a copy? A clear PDF would be fine, or even a series of clear JPGs.

I found a place where one can order the manua; for this signal generator. They also carry manuals for a LOT of other equipment, and are a resource you may want to add to your list of bookmarks as I did. https://manualman.com/index.cfm?v_link=main   By the way, they take PayPal as well as checks for payment. I'm glad, because PayPal is my preferred method for online buying.

Congrats. I've heard and read that Jackson made some good test equipment. I've never owned any, though, so I can't speak from experience.
