SP-331

Hybrid Stereo Power Amplifier

Proven technology. The SP-331 end stage processes the input signal via two 6N16 valves each. There are 12 TOSHIBA end transformers provided for the power in each case. The SP-331 can also be operated at 2 Ohm without difficulties. This is ensured by a ring core transformer with over 1,000 watts and filtering of 80,000 μF per channel. The result: beautiful sound and deep basses.
