TRIODE TRV-1

Commentary

A tube type preamplifier designed to drive the power amplifier 845 Signature.

By minimizing the number of additional circuits, we can obtain high S/N and low distortion signal output. The power supply circuit is fully integrated into the power supply circuit so that the power supply circuit is condensed in 60% of the area of the amplifier chassis.

A power transformer and a choke transformer are located inside the trunk case.

The power supply is equipped with a 30-second relay that operates when the power is turned on to protect the vacuum tube.

6N high-purity RCA cable is used for internal signal wiring.
The power cable uses μ -PS15, a high-grade power cable from Furukawa Electric.

TAOC-made special insulator is mounted on the leg part.

Vacuum tube cover bonnet is included.

The design of the knob part seems to be different between the early stage and the later stage.
It was equipped with a gold knob in the early stage, but it is equipped with a silver knob in the later stage.
