A friend dropped an inexpensive audio oscillator by for me to check out.

Some interesting stuff on that web site. It's pretty cool that they're into selling kits, as the outfits that used to ain't doing that any more.
This oscillator has a claimed distortion of 2 parts per million (0.0002%).
I don't see where I would need something like that.
I only have access to test equipment that can measure down to 0.001% and this oscillator's distortion was lost in the noise floor of the test equipment.
The frequency was slightly off, well within specs but 1002.31Hz.
For strictly analog, that ain't too bad.
At $89 this represents an amazing value. Yes you can download their assembly manual and "roll your own" but I doubt you can achieve the performance of this unit.
I looked that over, and some of the other ones.
Part of their magic is their PCB layout and hand selecting the frequency determining devices. It isn't worth my time and energy to try and copy their PCB and locate accurate parts.
I'm well know as a cheapskate and I ordered one.
What are you going to do with it? Me, I'll probably end up rolling my own of various amps and things. I do have an HP audio generator sitting back there that I picked up at a hamfest that needs a little TLC. One of these days...
