Self's aim is casino la riviera avis a low-dissipation class-A amplifier, whereas my goal is a non-gm-doubling output stage that runs primarily in a rich class-AB.
In other words, the new mono octal PCBs are headphone-amplifier friendly, which leads to the following design techniques.
Indeed, I have posted so many balanced tube poke bowl chicken calories circuits that Google should be giving me a kickback for all of schematics that show up in their image search results.
Well, relief is on the way.Since 1980, I have been reading about audio's impending demise.In other words, the current amplifier is the alternative universe reflection of the voltage amplifier.Broskie Sliding-Bias SE Amplifier To transition push-pull class-A operation into lean class-AB operation requires a drop idle current.Although I find this prejudice silly in the extreme, I must acknowledge that it is widely held.Super Symmetrical Cathode Follower This modified cathode follower both rejects power supply noise and produces less distortion.The following power buffer uses a 6AS7-based OTL output stage.Simple Push-Pull I-to-V Power Amplifiers Now that we have examined some simple single-ended I-to-V power amplifiers, we can move on to their push-pull brothers.



Single-Ended White Cathode Follower The White cathode follower is a unity-gain, push-pull buffer, which also makes use of a current-sense resistor to establish an anti-phase signal for the opposing output device.
Ew Unbalancer PCB After many a season returns the Unbalancer.
Well, I decided that it was time to actually build a tube circuit to mate with the Chromecast Audio puck.
But it does terminate the output transformers primary into ground, which allows us to apply a negative feedback loop from the input tubes cathode to the output transformers primary, which will lower the amount of power-supply noise making its way to your loudspeakers.Next, he wonders why there are two 1k resistors across the differential outputs.Mosfets, transistors, jfets, and pentodes all offer transconductance, the ability to efficiently control current conduction through an electronic device, but only the triode presents a low parallel resistance.Crossover-Notch Distortion (continued) I know that many ardent tube lovers tuned out on the topic of crossover-notch distortion and mixed-mode amplification.Post 216 and Post 217 are a good starting points.Super-Simple Differential MC Pre-Preamplifier The following design offers stellar performance and yet uses few parts.Introducing an Old Friend: The ccda As a response to the darkening economic sky and the big success that the All in One PCB and kit have been, I have resurrected an old trusted circuit that is tube-stingy, the ccda line-stage amplifier.
