Hybrid Class A stereo power amplifier

20th Anniversary Edition

20 years of Vincent!

For the jubilee, we offer you a special model, the SP-20. This is a studio hybrid power amplifier which in its base is founded on one of our most successful models, the SP-331 MK.

We have thoroughly revised the unit and optimised the circuit In addition, we made a facelift and gave it 2 VU meters.

The speciality; the colour of the background lighting of the control instruments is adjustable. You can choose between red, blue, green and white with a switch on the backside of the unit. The exquisite aluminium case with its impressive cooling fms hiding and indicating its great power remains unchanged.


Two 6N16 tubes working in differential push-pull mode form the input stage. The more powerful 6N10 tube transmits the signal to the transistor output stage 12 FET transistors amplify the signal. The signal amplifying is supported by 8n electrolytic capacitors with respectively 10,000 yF. These dimensions deliver enough power if necessary and it is possible to operate even critical loudspeakers adequately.

The power amplifier presents itself in the guaranteed Vincent style. The basses are precise and powerful whereas the mid and high signals sound and transport. Thanks to the tube, it brings a warm and clean sound emerges from the init.
