In anyone was interested in doing this, rather than pay the $35 dollars that the amp builders charge, here are the directions on how to wire up a remote switch for your amplifier......
Parts needed....
1. Stereo phono jack (1/4")
2. Any type of wire. Actually the thinner the better.
3. Any type of switch you may want to use.
The stereo phono jack has 3 conductors, one on the end, middle, and shield for ground. Wire 2 wires to a switch and the other end to the tip of the connector and the other wire to the middle section - NOT the SHIELD. Leave the outer part disconnected. The wire can be small due to the fact the switch controls a relay anyway and has very low voltage. Once completed, it should look something like this:

And there you have it. Of course this will only work with the amplifiers that already have the 1/4" input from the builder.
