Up for sale here is this new Schadow SDU3P power switch.  This is an extra-fancy switch and is the correct replacement for a number of switches on some vintage NAD, Realistic, Marantz, Concept, Sanyo, Luxman, and other receivers from the 1970s and 1980s.  If your old switch looks almost exactly like this, this is probably the correct power switch for you.  If it doesn't look like this, this is probably not the right switch.  

This is identical to the old Alps SDU3P power switches, except that it has no metal mounting bracket.  You will need to carefully remove the metal mounting bracket from your old switch, install it on this switch, and then install this switch.  It's actually really easy.

You will most likely need to install a snubber capacitor for this in order to protect it.  I have those available here, if you don't already have one.

Installing this is simple--just wire it up exactly like the old one, using the new snubber capacitor to replace the old one. If you don't see a snubber capacitor attached to your power switch, just wire it across the AC terminals.
