The other really great th8ng about many older non digital boards is that fixing them is relatively simple....most people with some electronics training can replace capacitors and resolder pots or change out a jack. The guys in my old bank used to fix stuff like that all the time on amps...and really same with the 2 mixers I had. Moral if this story....even selling a "parts" or needs repair board will get you more than scrap...the th8ng would have to be completely hosed or ran over to go to the scrap pile. And trust me I understand....I dont mess with stuff that I will only make a few extra $$$ on...that stuff goes to the yard and I dont bother...ie not $50/hr in value for.my time then scrapped....the upside here is enough for your time.
