The Vintage Series Amplifiers

The Vintage Series Class A Amplifiers

These amplifiers are designed and built by Bedini Electronics Inc in Coeur d'Alene Idaho. The amplifiers are gathered over the thirty eight years from John Bedini's private collection of the best sounding circuit designs. We at Bedini Electronics went to John's basement and started going through all the proto-type amplifiers, Pre-Amps, tubes, ect. We hooked up the proto-types KT88 tubes to the Shahinian Diapason Speaker System,  listening to the tube amplifiers we could not believe what we were hearing out of these 10 watt mono block amplifiers. John said that he was saving the amplifiers until the industry gave it, it's best shot and then He was going to bring this vintage amplifier out to market at a price everybody that loved music could afford. The amplifiers pictured below are the proto-types of the KT88 Mono Block that we are going to start production on, starting in December. The amplifier will only be built in the "Vintage Packaging" .

Sign wave of the model 10 Mono Block SE, notice how the sign wave looks at full power before clipping at  11 volts RMS into 8 ohms which equals 15.125 watts. The wave looks just like most of the solid state amplifiers. John explains it's the way the auto feed forward bias is connected to the tube cathode and wont give any more details about it. I have seen this amplifier clipping, and both wave forms clip symmetrical. So here is what I have done, I went and looked for pictures of sing waves of what, others considered to be the best output into 6 to 8 ohm  loads and what they look like, look for yourself at what the difference is. The Tektronix is the Bedini Amplifier at full power, the other is one of the best they claim. Judge for yourself !!!!

Notice how the two amplifiers reproduce the wave forms. Bottom picture is your typical SE tube amplifier at full power. Top picture is the Bedini SE amplifier.

John sometimes tells the story of how He, and Saul Marantz , Stewart Hegeman use to talk for hours at the CES shows about special tube circuits and how they worked and what could be done to make the amplifiers sound the best, and I believe it after my listening to this amplifier.
