Tom, A great idea (why didn't I think of that). I don't cart my K3 around much, but I use 2 speakers for AFX. It is not 'nice' having both speakers tied to a single stereo jack. Another solution, although not as elegant, is to use a Y-adapter. If it is a commonly manufactured adapter, the ones that adapt 1/8 inch stereo jacks will not work because the plug and two jacks are simply wired in parallel. The Y-adapter with a 1.8 inch stereo plug to 2 RCA jacks will work, but it requires RCA plugs on the speakers (or that addition of 2-RCA plug 0to 1/8 inch jack adapters. One example is from Radio Shack: Y-Adapter, Phono Jacks to Stereo 1/8" Plug *Model:* 274-269 | *Catalog #:* 274-369 Tom, I will take one of your board if you decide to make up some 'kitchen boards'.
