Yeah, I'd keep it, and try Phil's string recommendation. We have a 50s Harmony bari, we restrung it and our luthier put new friction tuners in, but it still won't stay in tune, but it's been good enough to teach me that I don't want another bari. I doubt if we'll spend any more $$$ on it, but we'll keep it for it's classic value. A friend has a 60s Harmony soprano in excellent condition and it sounds great.
