I just ordered sixteen 22" Samsung LED TV's for my company to install. Unfortunately they did not come with the usual headphone jack on the back. The only solution is to bypass the internal speakers and run the wires into some kind of circuit that reduces the voltage to headphone level. Many years ago Radio Shack used to sell a device the size of a D cell battery that you wired to your speaker outputs of your amplifier and could plug a 1/4" headphone jack in the other end. Simple. 10 bucks. No such thing anymore. Does anyone know how to build a circuit that would do this ?
Or could you direct me to wesite that does ?
Appreciate it thanks.

Google "L-Pad" values can be tuned and tailored to match your system with some trial and error... I would try a 1:3 or 1:5 ratio for starters...
