Here's the cable that should work.
In addition to the cable you'll need a pair of RCA to 1/4-inch mono adapters, which is also available at Radio Shack. I have a couple of the adapter plugs here, but I cannot find the Radio Shack part number for them. Their were two in a pack and sold for about $6.99.
Good Luck,
Gary
