Pair of solid copper jumpers for integrated amplifiers / receivers.

The Marantz 2270 & other 22xx series amps use 17mm jumpers.

17mm seems to be the most common size, but other amplifiers use 19mm, 14mm, 11mm.

Let me know if you know what size you need. Unfortunately I don't know what size every amplifier uses so I will need either measurements or a photo with ruler showing center to center distance.

McIntosh uses a smaller size. 4100 & 4200 use 11mm. 1900 uses the regular 17mm.

If you need a custom size, choose "custom" and leave a note as to what size.
