Selling one pair of Wavelength Gemini 45 mono amps in very good condition. Can also use 2A3 tubes via an internal switch accessed through the bottom of the amp. Uses 6V4 rectifier and 5842 input tubes in addition to the power tubes. Amps will come with SYLVANIA 45 output, TELEFUNKEN rectifier and WESTERN ELECTRIC input tubes. These amps , when used with Horn Speakers, sound spectacular.
Gemini, the name chosen for being a twin is a single amplifier that can be optimized for two different output tubes, the 45 and 2A3.
The circuitry can be changed using a switch inside the chassis for either of the two output tubes. The circuitry has two stages, the input connected to a 5842A/WE417A. The output of the gain/driver stage is capacitor coupled to the 45/2A3. The power supply is choke loaded for better dynamics. Power is rated between 2.5W (45) to 5W for 2A3's.
When the switch is changed between the two modes, each of the tubes is optimized to the best of it's performance. As in all Wavelength Audio products the power supply is tube rectified (6V4/EZ80) and uses the best components from MagneQuest. Black Gate and Shinko.
