Model no: SE-300B-Super

This is one of our state-of-the-art single-ended power amplifiers, using the most common 300B (or 2A3 , 45 , 50..etc ) medium power tube as the output section. A high grade silicon-steel 15W 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 XLR balanced input in this unit can further enhance the depth and width of the sound stage by 20-30%, with additional air and solidity in the bass control. Definitely an up-grade from the RCA input version.

A 4ohm or 8-16 ohm selectable output switch is featured for correct impedance matching to almost any speaker. 16ohm speakers can also use the 8 ohm output setting for increased performance.

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

This version is the Universal tube version with 2.5V/5V filament supply voltage , 3.5K/5K of transformer primary impedance can be selected to get optimum performance for different power tubes. Also equipped with L and R channel gain balance control to balance any un-even gain of tubes (very important when use NOS tubes) , active high-pass filter mode can be set to use in Bi-amp system to prevent low frequency power waste, so 8W can sound like 20-30W if only drive the mid-hi section of the speakers.

option : Tube model 50 need 7.5V filament transformer upgrade

(optional chassis : Mirror steel, black piano , solid-oak )
