TUR-08 真空管とハイパワートランジスタのBTLヘッドホンアンプ

TUR-08 High power Balance output TUBE × TRANSISTOR HPA

Production period: 3 month


TUR08 has the power to sufficiently drive low-efficiency headphones such as flat drive and open air, Inherited the Clarity of the TUR series and the dynamic feeling of the tubes.
The internal is composed of a tube preamplifier section isolated from electromagnetic field noise and a powerful buffer amplifier section of eight power transistors.
It is designed to bring out the ideal characteristics of parts and headphones by adjusting the operating range of the tube checking the Level meter and continuously changing the gain level.

SUMALLY
