RELEASE DATE: APRIL
£TBA

The new VS70.1 from JE AUDIO

# Fully balanced input (also has separate RCA input).
# Fully balanced output (no loudspeaker terminal is connected to a ground terminal).
# Patented Dual Balanced Feedback Topology (DBFT) improves signal integrity and audio fidelity.
# Stereo 2 x 40W output (2 x KT77 power tubes per channel) with premium power supply.
# C-core filtering choke and premium capacitors are used in power supply filtering circuit.
# Output transformer uses premium grade M6 grain oriented steel imported from the United States. The primary side is connected in the Ultra-linear configuration and the secondary side in a proprietary full balanced configuration.
# Power transformer uses premium grade grain oriented R-Core imported from Japan. Low noise and high efficiency ensures minimum temperature rise from the power transformer.
# Premium grade copper foil in oil type signal capacitors for signal coupling.
# Fixed biasing is used for power tubes. Biasing current for each tube can be adjusted individually.
# Soft power-up circuit reduces the inrush current when switching on. It also ensures that in the first 60 seconds only a reduced supply voltage is applied to all vacuum tubes. This prolongs life of all rectifying diodes, power supply filtering capacitors and vacuum tubes.
