The Copland CTA407 amplifier allows you to use any model of the 6550/KT88/KT120/KT150 family as output lamps – the proprietary lossless automatic offset adjustment system will determine the optimal operating mode of the selected lamps. The Copland CTA 407 is supplied with KT88 lamps in the output stages, two 12BH7 dual triodes and one ECC83 dual triode in the pre-amplification stages.
