jafant, it was sold as a nominally 100wpc stereo power amp. Steve McCormack's estimates of mine is 125/250/500 wpc 20-20k@<1% THD into 8/4/2 ohms, absolute stability into 1 ohm, and as much as 60A peak current delivery depending on the measurement technique.
Most of this power improvement comes from barely fitting in the custom Plitron power transformer designed for the DNA1 upgrade.
Overall negative feedback has been reduced to 3-4dB (which is nearly zero by today's standards) and it will pass DC (at a much reduced level, and hopefully not) to the outputs all the way up to a 250kHz -3dB point, intentionally rolled-off to prevent ultrasonic issues...
