combiner

Ive attached a schematic of a little combiner box I made up for use with interfacing a guitar or other mono input amplifier with a stereo, dvd, headphone or satellite receiver.  It can combine the signals through the RCA jacks to either a mono or stereo 1/4" jack.  The resistors in line assist with the mix, as well as keep a certain level of separtion between the channels. The can be anything from about 32 ohms to about 100 ohms.  To interface with a 1/8" headphone, I picked up a 1/8" stereo to twin RCA plug cable from radio shack.

I've attached pictures of the outside and innards of my "combiner/converter".  I bought the tin of candy for about $0.50 - candy was good, but I bought several just for the tin box!
