70Wrms x 2 single-ended 300B power amplifier

This is our high power series of single-ended 300B power amplifier, which inherite the sweet and smooth airy sound of the pure tube version of 300B amplifier, and at the same time process the big dynamic and high power driving capability. Now you don't need to use super high sensitivity speakers to work with your 300B, but free to use whatever speakers, and still can fully utilize the super sweet character of this tubes.

This amp features the following mind-blowing characters:

1. 0db NFB from input to output , 300B is working in pure class A single-ended operation mode, and point-to-point hand wired with gold plated sockets

2. 300B is really for amplification of the music signal, not like some others just use 300B in the power supply section and claim to be a high power 300B amplifier

3. No output transformers (OTL design), maximum damping factor and most widest bandwidth can be achieved, the beautiful characters of the 300B is totally exposed, the bass control and richness is so good that exceeds any traditional 300B designs while the mid and high range sweetness and silkiness still holds.

4. Super low noise level, you can hardly hear such quiet background from old-school single-ended 300B design

5. No bias calibration , no hum adjustment or any maintainence needed, the 300B tube works under a totally safe and long lasting operation condition, which can almost last forever until the filament die.

6. Super low cost per watt . Typical 300B amp charge $300-$400 per Watt , this design only charge 1/10 of the cost.

Option: Solid-oak chassis with black top plate add $300
