Auction is for one set of two Preamp-out to Power Amp-In (Main-in) jumpers.

Many vintage receivers are designed with external connections between the preamp and poweramp.
This allows the user to operate the receiver as a preamp connected to an external poweramp.
When used as a single component-receiver a jumper must be used to connect the preamp-out to the poweramp-in (Marantz calls it Main-in) outputs.
 
The McIntosh 1900, 4100 and 4200 receivers use smaller jumpers that are 7/16" or 11mm wide.
The Marantz 2200 series, Kenwood, Sansui and Pioneer use larger jumpers that are - 5/8" or 16mm wide.

If unsure which ones your receiver requires, please measure the distance (center to center) between the preamp-out and poweramp-in connections on the rear of your receiver before ordering and specify which size you would like.

Before I can ship your order I will need to know what size you want.
