Features:
This is a single stereo power amplifier using the
6BM8 vacuum tube that has a five triode for power
amplification and a triode for amplified voltage. Assembly is easy. Anyone can follow the
printed circuit board and obtain the same result. For
this reason, you do not need to know the details of
wiring and other technical details to assemble a vacuum
tube.
This
amplifier installed with advanced "R-core
transformer" as a power transformer that
enables clear tone quality. To improve transient
characteristics.

This set
includes a tube protector to decorate and an
electrolytic capacitor for bringing it up to
specification.
-
This
meshed protector brings out the TU-870R design and
also this prevent you from touching the vacuum tubes
by accident.
-
Electrolytic capacitor reduces 30~40% residual noise
by installing it on the "OP-C" of the circuit board.
