The EOS integrated amplifier is the most powerful integrated amplifier in the Trafomatic Audio line. It is built according to a push-pull circuit with KT 120 output lamps. The output power is 100 watts per channel, which should be more than enough for the vast majority of speakers, even with low sensitivity. A full amplifier combines the functions of a preamp and a power amplifier. According to the manufacturer's research, the optimal negative feedback value has been selected: minus 6 dB.
The "dual mono" principle is implemented in the design of the EOS+ power power amplifier. The new, well-proven KT150 Tungsol output lamps are used in the push-pull output stage. 150 watts of power per channel is more than enough to be compatible with most speakers, including low-sensitivity ones. EOS+ power is a "pure" power amplifier. A preamp should be used in conjunction with it, which will help adjust the system configuration to your own needs.
