8W x 2 single-ended power amplifier

This is one of our state-of-the-art single-ended power amplifiers, using the most common 300B medium power tube as the output section. A high grade single-ended output transformer is used to ensure the highest sonic quality. This amplifier can drive speakers with efficiency above 85db/W, or it can used as the second amp to drive the tweeter section of a bi-wired speaker system.

The 300B has a very sweet and transparent characteristic which makes it very suitable for classical music, vocal, and jazz reproduction.
