Περιγραφή
Μετά από αρκετά επιτυχημένα χρόνια, η εταιρεία ανανεώνει τον κορυφαίο προενισχυτή αναφοράς της. Ο SA-T7 εξελίσσεται πλέον στον SA-T7 MK.
Εκτός από τον εκσυγχρονισμένο σχεδιασμό του, διαθέτει πλέον και είσοδο Bluetooth, επιτρέποντας την εύκολη μετάδοση μουσικής από οποιοδήποτε κινητό τηλέφωνο ή tablet απευθείας στη συσκευή.
Still used is the BestPentode-circuit by Dipl.-Ing. Frank Blöhbaum, which eliminates the electrical cur-
rent noise typical for pentode tubes. Because modern signal sources have different requests to the
transmission quality of an amplifier, traditional (classical) circuit technology and ECC81/82/83/88
does not cover the full potential of tube technology.
The BestPentode stage we use has a much higher gain with less noise than comparable triodes.
The E180F / 6SCH9P / 6SCH51P grid pentodes used in the SA-T7 MK can thus develop their full
potential. The tubes are a new old stock (NOS) from storage that was used for amplifying high-
frequency signals 24/7 in telecommunication.
Thanks to the BestPentode circuit technology used in combination with the exquisite Vimala power
supply pairing, a highly linear amplification with almost no noise and outstanding speed for the best
possible musical enjoyment is created. We at Vincent are very proud of our SA-T7MK, because it is the
peak of many years’ experience in constructing innovative tube amplifiers. Innovation to fair prices that is
developed and finally assembled in Germany.
