This is a restored Heathkit IG-82 Sine-Square Wave Signal Generator. The signal generator operates through audio frequency range and beyond. This is a very handy signal generator for aligning the 50 KHz IF stage of the Hallicrafters SX-100. RF signal generators will not go low enough to generate a 50 KHz signal, but using this signal generator the alignment can be performed.

Was wondering if you might have a pdf manual for this unit that could make a donation or something?
I don’t have a pdf copy of the manual. Try here: http://www.vintagemanuals.com/manuals.php?manufacturer=Heathkit&page=1
Great job! I’m just about to tackle one myself. For anyone else interested, the AG-10 is virtually identical, and a full scan of the manual is readily available.
Paul, thank you for that USEFUL tidbit!
