Default Full range class D amplifier

Anyone got a schematic or info for a 20-20KHz class D ampliifer that can run off +/- 75 volts?

Some of us do

Sorry, bad joke. There still isn't a really good and immediately useful design in the public domain. If you want to experiment and to learn, follow threads like "Development of a "reference" class D starting point", "Thinking of starting a 'new' Class D design", My fully discrete ClassD" and a few others to see the directions in which others are working. If you just need an amp quickly, several diyaudio members here sell (or work for companies that sell) ready-made modules. Not naming any, but it shouldn't be too hard to figure out who.

There are a number of Class-D designs in the class-d section of www.schematicsforfree.mattsoft.net. Look in the Audio\circuits section.
