This is the full unused RE-909 kit. It includes all the circuit boards, switches, buttons, etc. to build an exact copy of the TR-909 internals. 
This kit is an exact copy of the TR-909 so you can use these parts to repair your TR-909 or build a brand new unit.
This will also include a rare parts kit worth over $100 alone.  This item is in the US already so you don't have to worry about Tarriff or import fees.

Please check my other auctions for the outer shell that goes along with this kit.
