Rega IOS MC Phono Preamp. This unit is a store demo unit and has at least a year of warranty left on it. We are authorized dealers for Rega. This unit has been recently discontinued from the Rega line. That is the only reason we are selling your demo unit. Please note that there is a 3% fee for the use of Paypal. The Rega Ios is a four stage all symmetrical amplifier. To provide optimum performance it is dedicated to amplifying the very low level signals that are generated by moving coil cartridges. The first stage uses a 1:10 step-up transformer, which can be optimised to the cartridge by the selection of the correct loading and zobel DC resistance correction network connected across the MC transformer secondary. The second stage is symmetrical compound pair class A amplifier, using paralleled low noise Hitachi transistors in the input stage. This drives the passive high frequency part of the RIAA equalisation stage. The third stage is a symmetrical class A differential amplifier with a common base driver stage; this is also used as the active amplifier in the low frequency part of the RIAA equalisation stage. The fourth stage is the active filter, this configuration uses the same circuit as found in the second stage. The filter element uses a very high bandwidth operational amplifier gyrator as the simulated inductance part of the tuned filter.
