kungfugeek,
Don`t search for a signal generator on the web, you get mostley answer for a RF-generator. (usable in the high frequency region)
Search for a audio oscillator and you get a lot of them on the web.
There are a plenty of the old Hewelett & Packard 200 AB/CD series tube audio oscillator, and you can get very cheep on e-bay, this is a great work horse that will continue to survive the mostley of the other audio oscillators. (as it already have done since the 1960`s)
But Eico, Heathkit, Leader, Tech, Trio and many other brands is very nice for hobby use.
