# Two output power tubes per channel in push-pull configuration # Made in our laboratory high definition output transformers


The input stages has three double triodes tubes, one 12AX7 and two 12AU7.

The output stages with two 6L6GC tubes provides 50W per channel.

The stereo power amplifier VIA-50 has a very compact design.

The chassis configuration houses the 200VA toroidal power transformer and two output transformers.

As with other Audio Technologies models constant current sources in the input stages, help maintain stable drive characteristics and balance of the output stage.

VIA-50 vacuum tube integrated amplifier is capable of high level resolution and control over any loudspeaker with vivid and natural presentation.

The VIA-50 vacuum tube power amplifier delivers modern performance standards, with all the features to meet the needs of today’s music.

As with all Audio Technologies amplifiers it will provide ultimate stereo separation.

50 watts of power is output into a speaker load with less than 0.5% distortion.

A small amount of negative feedback is applied.

Audio Technologies special design provides very low distortion, extended frequency response and long tube life.

VIA-50 oversize power transformer provides high power and dynamic response from two 6L6GC output tubes, setting a high performance on tube amplification.

Balanced and unbalanced inputs allow matching with all solid or vacuum tubes preamplifiers.






# Δύο λυχνίες εξόδου ανά κανάλι σε push-pull διάταξη # Κατασκευασμένοι στο εργαστηριό μας υψηλής ανάλυσης μετασχηματιστές εξόδου


Τα στάδια εισόδου χρησιμοποιούν τρείς διπλοτριόδους λυχνίες, μία 12ΑΧ7 και δύο 12ΑU7.

Τα στάδια εξόδου χρησιμοποιούν δύο 6L6GC λυχνίες που παρέχουν 50W ανά κανάλι.

Ο στερεοφωνικός ολοκληρωμένος ενισχυτής VIA-50 έχει έναν πολύ συμπαγή σχεδιασμό.

Η διαμόρφωση του σασί περιλαμβάνει τον 200VA τοροειδή μετασχηματιστή τροφοδοσίας και δύο μετασχηματιστές εξόδου.

Όπως και στα άλλα μοντέλα της Audio Technologies, πηγές συνεχούς ρεύματος στα στάδια εισόδου, βοηθούν στη διατήρηση σταθερών χαρακτηριστικών οδήγησης και ισορροπίας του σταδίου εξόδου.
