New Audio Frontiers Stradivari tube preamplifier NEW


New Audio Frontiers Italy Stradivari Line tube preamplifier was designed to meet the highest demands of audiophiles. 

Stradivari implements high voltage power supply, that uses very high gain error correcting stage based pair of 12AX7, that are driving a 6CA7 power tube. Circuit has been optimized to eliminate any parasitic oscillations and maintain a constant anode voltage and a ripple lesser than 250 µV. The excellent filtering and the use of circuit voltage regulators provide the DC voltages to the heaters for the left and right channels and everything was measured on the top grade HP and Tektronix lab instruments.
