The Unison Research Triode 25 Black Edition integrated amplifier supports two output stage modes - triode and pentode. In triode mode, the amplifier raises a power of up to 30 Wt per channel, and in pentode mode - 50 Wt. The pre-amplification section uses two ECC83 Gold Lion dual triodes and one ECC82 Gold Lion. The output stages uses four KT77 Gold Lion tubes (a pair per channel), operating in push-pull mode.
