Beskrivelse

A highly versatile vacuum tube phono preamplifier with
MM and MC gain and unique on-the-fly adjustable
tone control facilities. The frequency response of the
amplifier can be controlled within wide limits by varying
the edge frequencies of the de-emphasis characteristic
via three 6-position rotary selectors (tone selectors).

As a side effect of this unique concept, the entire range
of phono equalization curves used by the prominent
record companies throughout history
(including those of pre-microgroove 78-rpm era)
can be activated or at least closely approximated
by choosing appropriate
tone selector settings.

Generell info

•6 phono inputs with gain pattern (5xMC+1xMM) and cartridge loading (100, 200, 300, 500, 1000; 47.000) ohms. Alternatively, a gain pattern (1xMC+5xMM) can be implemented on request.
•MC gain with state-of-the-art signal-to-noise-performance in purely active operation mode (without the aid of step-up transformer gain).
•Minimalist single-ended zero-feedback schematic with passive de-emphasis installation utilizing (2x12J5GT+2xPC86) vacuum tubes.
•Edge frequencies of the de-emphasis characteristic independently on-the-fly adjustable within wide limits by means of three 6-position rotary selectors. Realto-reap tape NAB and IEC equalization settings can be installed on aside the phono settings on request.
•Entire range of phono equalization characteristics used by the prominent record labels throughout history can be activated by choosing appropriate selector settings. Equalization settings suitable for 78-rpm playback included. Highly accurate RIAA equalization with tone selectors in default position.
•Subtle yet highly effective tone control facilities for restoring tonal imperfections of the vinyl program, implemented without the aid of clumsy sound-degrading conventional tone control circuitry.
•3 outputs (RCA terminals) with very low output resistance.
•Full hand construction, point-to-point wiring throughout.
•Ultra low noise mains transformer produced in-house for 230Vac (115Vac via jumper setting), 100Vac (Japan), 120Vac (USA, Canada), 220Vac (South Korea, China, Thailand, Indonesia), 240Vac (UK) or 245 Vac (Australia).
•220Vac (Thailand, China-ML, Russia, Korea, Indonesia, 100Vac (Japan) or 245Vac (Australia) available on request.
•Non-magnetic aluminum casework, front and rear panel with anodized printing, powder coated lids.
•Dimensions: 434x434x154 mm, 154=134+20 (case feet).
•Dimensions of the shipping box: 650x650x350 mm, weight 11.6Kg.
