Preamplifier

SONO

Symmetrical valve preamplifier

Dual mono build.

Frequency response: 5 Hz – 400 kHz / – 3 dB at 1 Volt
Output impedance: max. 600 Ω balanced
Input impedance: min. 20 k Ω

Dimensions: 480 x 133 x 370 mm / weight: 11 kg

Ultralinear double triodes with high power supply ability,
it is possible to achieve single-stage amplification without negative feedback. By coupling amplification stages, any forced distortion which could arise
from multistaging is avoided; the amplifier is particularly low-noise
(and consequently suitable for the ORGON). A valve device of the finest: unbounded dynamics, natural and adjustable.

Shunt speaker regulation i.e. no voltage regulation along the signal path.

4 Line inputs – symmetric
1 Line input – asymmetric
2 Outputs – symmetric
1 Tape output – asymmetric

With 2 power supplies, starting logic for valve protection
and loudspeaker remote control. Design integration is possible.
