Short term (or "music") power is typically about 240W into 8 ohms and 380W into 4 ohms. With the full supply voltage of +/-70V (which must not be exceeded!), RMS power is around 180W into 8 ohms, or 250W into 4ohms. The only change that is needed is to trim the MOSFET bias pot! Indeed, it will operate stably with supply voltages as low as +/-5V (completely pointless, but interesting), all the way to the maximum supply voltage of +/-70V. This amplifier is designed to be as flexible as possible, with no bad habits.
