This is an old Futaba separate-type amplifier for RC cars. It's probably rare because it wasn't a very popular model at the time. This item is non-functional due to a malfunction. The blue part of the main unit has a few scratches on the back. Otherwise, it's in good condition with few scratches. The wiring and connectors are in their original condition. The case and instruction manual are included. It would be good for display in a vintage RC car. Please understand that this is an old item, so only those who can accept its condition should purchase it. No claims and no returns, please.
