The tubes used in this project are a pair of 12AX7 or ECC83 NOS, as the first gain stage in MC, the second stage is made with the help of a pair of 6922 or ECC88 always NOS with the attached passive RIAA network connected at the pre-final stage of 12AT7 or ECC801S.
Last stage in current but with hybrid technology operating in pure Class A is made with an excellent Triode of the Siemens CCA series, half per channel that drives a pure class A polarized stage of high current Mosfet, ensuring an output level sufficient to drive any preamp stage with an impedance value of approximately 10 Ohms per channel.
All power supply stages with a solid-state electronic stabilization system differentiated for each single section and gain stage with an attached inductive capacitive load (in order to improve the signal-to-noise ratio and consequently the resolution in terms of timbre and dynamics).
Separate power section.
