The first two, between which has been inserted the network R.I.A.A. equalization, are used for the amplification of the signal coming from a cartridge of the type MM, while the third performs a lowering of the output impedance in order to be able to drive without no difficulty line stages which have a low input impedance and / or high capacity due to interconnecting cables also rather long.
For the use of pick-ups of type MC, further amplification has been delegated to two transformers STEP-UP, one for each channel, with the mu-metal core and windings in silver rather than to a further stage of the active type in order to reduce noise and maintain high quality sound. In the front was inserted a potentiometer in order to be able to adjust the load of MC pick up.
Within the device has several peculiarities. It was adopted the choice of using the solution of 2 frames in order to minimize any problems of uptake of electrical noise coming from the power supply. In the latter the straightening of the anode voltage is implemented through a dual triode vacuum type EZ 81 and level out by two cells with PI Greek inductive, one per channel.
The power supply of all the filaments of the tubes tubes of the signal is, contrariwise, stabilized. Another special feature is that of having chosen to realize a printed circuit where the path of the tracks is identical in both channels to make sure that even the smallest and unavoidable parasitism capacitive are identical between them. The components have been chosen at the highest level which includes and especially stand out the capacitors MICA SILVER used in RIAA EQ, high stability, low loss and minimum tolerance. All this to say that in addition to the technique is also especially our passion to respect the music, certain that the amplifier phono STRADIVARI will give you the opportunity to discover new emotions with a unique listening experience!
