Tube based audio oscillator, I've had this for years and just never really use it. I got it working last year and played around a bit, works fine aside from a couple of switches needing cleaning. One of the knobs is not original but otherwise it's all there. I considered selling it on eBay but it looks like they are plentiful and don't really fetch enough to be worth the effort so I'm offering it here for free to someone who will use it, please no hoarders who already have 5 of them.
Just pay shipping from 98072, it weighs probably 7 lbs so ~$10-$30 depending on what part of the US you are in. Willing to send international but likely not economical.
