A power amplifier that can output 150 watts in stereo and 300 watts in mono with a resistance of 4 ohms.
The PrimaLuna Evolution 200 Power tube power amplifier is built according to a push-pull circuit. The device is made in a classic metal case with an open lamp installation. The latter can be covered with a casing to protect them from accidental touching.
This stereo power amplifier can be easily switched to mono mode using the switch on the back panel. After that, your monoblock gets another tap at the output for a 2 ohm load (in addition to a 4 ohm and an 8 ohm), and two output transformers will provide better alignment with the speakers.
The PrimaLuna EVO 400 Power is the oldest of the four power amplifiers, producing 2 x 38 Watts of triode operation on EL34 lamps or 2 x 70 watts in ultraline mode. It can also operate on KT88 / KT120 / KT150 lamps, respectively, producing 2 x 43 / 2 x 45 / 2 x 51 watts in triode mode or 2 x 72 / 2 x 85 / 2 x 89 watts in ultralinear mode.
