Up for sale here is this power transformer from a Marantz 6300 turntable. It is in extremely good condition with light wear. There are a few discolored spots but those are from the factory finish. Please see my pictures for details.
US shipping and handling is $8, and international is $28. If you have any questions, please ask.
I have lots more Marantz 6300 parts listed--feel free to take a look! If it's not listed, I don't have it.
