This is one amazing tube integrated amp. Not only is it sonically superior sounding when compared to other tube amps – integrated and power amps, at this price point, it is also tremendously flexible and very well designed. PrimaLuna has listened to its customers and made the ProLogue Premium compatible with KT88 and EL34 tubes with just a flip of a switch on the side. With its proprietary Adaptive Auto Bias Circuitry, changing between these tubes is just a matter of swapping out the tubes and you are done. The circuitry in the amp will auto adjust accordingly to the tubes installed. Power output is 35W with EL34 tubes and 40W with KT88 tubes. Tubes in the input stage are four 12AU7s.
Unit is in very nice condition, just minor scuff marks common with use. Remote and original box included. The hefty integrated will be securely packed for safe shipping.
