That being said, though, do I have any options to test my SG-8 without a known good probe or frequency generator? Assuming that device is out of the question (which it sounds like it just isn't a good option for this) where do I start? It's starting to feel like this whole thing just goes around in circles unless I get a known good piece of equipment that I can use to test everything else.

Do you have amplified computer speakers or some audio amplifier with an audio input?...that's all you need to test the audio generator half of the generator. Any signal in the 100-5000Hz range will be fine for signal injection testing of audio.

I kinda make it a point not to buy scopes or any piece of test gear currently made broken...If there is a good used one I can afford then a broken one is not worth wasting my life fixing.
