Zen Variations 1

The Zen lightenment amplifier from Zen variations-part 1 (page 2 fig.5) I am using 2 300w Sylvania light bulbs (one per channel), IRFP240 and 75000 uFD in power supply with 4mH coil. ( THD,SNR and FR as expected, measured with AP system one) The amplifier sounds nice. Thanks Mario Ninic
