Model no: UPP-100-bal-Mk4
C$9,280 Untitled Document [US$ 7424]


100W x 2 class AB Universal push-pull power amplifier

This power amplifier is built with a special variable bias circuit which can drive 10 different types of output power tubes. With that degree of flexiblilty, the user can easily use the different characteristics of output tubes to match the whole system. An ultra-heavy power supply section gives you both good dynamics, and a sweet easy sound quality. This is a state-of-the-art power amplifier which you’ll find hard to resist. This amplifier is equipped with a true balanced input stage which can let you fully explore this type of architecture’s advantages. Also the inter-stage transformer enhances the sound stage and musical feeling of the recording.

The lower 2 set of photos shows a special version with a dual tube rectifier.
