It's a simple and robust design, pretty easily fixed with generic parts. That said it's also old. I bought an 8000C a couple of years ago for just under $200 USD. For that price it's a great unit (class A preamp, great headphone, switchable MM, MC phono).
I would not spend over $200 on the unit, less since the toroid is not original.
My guess is that a brand new preamp of comparable build and sound quality would be well over $500, probably nearer $1000.
