16 dB gain, zero feedback all tube line preamplifier, 500 ohms output impedance. Very short signal path from the 6 inputs to line or tape outputs. State of art components: paper ( or MKP ) in oil capacitors in signal path and PSU, carbon composite resistors, silk parts cathode capacitors. High selected NOS tubes ( two 12B4A, two 6J51p and one 5Y3GT ). Very quiet noise floor ensured by “floating” power transformer, CLCL filter plus dual Mosfet stabilized PSU and star ground technique. Voices, acoustic instruments, dynamic attacks, width and depth of the acoustic scene are reproduced in perfect way: Figaro -Reference Tube Line Preamplifier- takes you inside a concert hall.
