Putting out 8 powerful watts per channel this amp can drive most speakers. This amplifier has been designed by Gary Dodd of Dodd Audio. The amp can drive speakers with a 87db rating to very acceptable levels. I had it built for 230 volt operation, 4 or 8 ohm output. Construction details include only top line parts. Sonicap, Neutrik connectors, and more. A separate power box provides very quiet operation. By isolating the power supply from the output transformers this design achieves* less hum and better sound staging. The signal tubes included are 7044s, which produce a larger soundstage and more natural presentation than the 5687s, which are the other choice for this circuit.
The supplied pair of 300B's are the highly regarded Sophia Mesh Plates. The transformers are custom wound exclusively for this amp.*No one else has them. 10 H chokes provide the quietest possible with 5u4 rectification. Of course, being a single ended triode design, no negative feedback is used. Point to point wiring is included throughout and a minimalist design ethic is employed.* It is as close as you can get to just a wire and a tube.
The power supply for the 300B filaments is AC. Most amp builders switch to DC to reduce noise. The problem is that doing so completely takes the magic out of this legendary tube. It also shortens the life of your high dollar 300B tubes. All Capacitors used in the power supply are bypassed with film caps which yields a very rich, open sound. Proper shielding, routing of wires, and a separate power supply box result in AC being very quiet and the sound is superior in every regard. DC is the easy way out resulting in a very thin sounding amp. You have not heard the beauty of this tube unless you have heard it with AC!
