GD70 Glenn tells me you're the expert. I have a vintage Onkyo TX-37 w channels are cutting in and out. I love the sound of the unit (I'm a phono guy) but know a fix is likely way more than it's worth. Is the unit good enough to justify the fix based on today's standards or do I just buy new? And while I know you're not looking at the unit, what would be a reasonable ballpark fix cost for the described issue?
