I have an old Marantz PM6010 OSE amp which I have owned since new but has been gathering dust for 18 months because there is a fault on the balance pot. These amps are worth around £70 in working order, so mine won't be worth a lot, but it weighs a tonne so selling it on ebay is not practicle as delivery would cost £20 alone. Any other ideas in order to sell this? I have thought about a car boot sale and selling it as faulty but I would imagine the market for this is too limited. How much would this fault cost to fix? The right channel just often cuts out, and wiggeling the balance pot fixed this for a few minutes.
