A DIY Push-Pull (PP) 6V6 Tube Amplifier built following the Dynaco A-410 6V6 Tube Amp Schematic.
Figure 1: OddBlock KT88 Series 1 Tube Amplifier SchematicThe voltage gain (input) stage is a common Shunt-Regulated Push-Pull (SRPP) amplifier using a 5751 miniature dual triode valve. Other input tubes can be used in the driver stage, the closest match being a 12AX7 which will provide ...
More than a century after the invention of the push-pull amplifier, a myriad of different configurations has been developed, some of which require prerequisite knowledge of the operation of complex transformers. The focus of this application note is on the push-pull amplifier itself. An example s...
we will find that that at 36W of output, one output tube is conducting 320mA, while its partner still conducts 20mA. What we have is a sloppy class-A amplifier, as the tube's leaky turn off simply becomes a burden for the more active tube. Sloppy...
output signal also drives V3, a 6C4 triode wired as a class A amplifier. The 6C4 buffers the output and also inverts its phase so that the distortion and clean signals are sent to the mixer with the same polarity. Half of a more-common 12AU7 tube could be substituted for the 6C4....
I have seen a similar phase inverter in theAudioResearchVT100 reference amplifier where a mosfet has been used instead of the fet to create a current generator. SCHEMATIC In the triode connection the power is limited and the damping factor is not enough good also if we use the cathode feed...
(and one Asian tube amplifier company), but I don't know how many have built it. The need for a negative power supply rail will daunt many tube-loving DIYers. (Click here for aschematicthat shows how a faux negative power supply can be created with a single, non-tapped secondary ...
The power stage is a class B push pull amplifier and as already stated, when one tube increases conduction the other decreases it by the same amount. Such a topology has very big advantage over single ended designs. In the output transformer, theoretically currents are equal and opposing, whic...
A high-performance, distortion-free, audio push-pull amplifier has a class A driver stage that drives a class B push-pull output stage that is coupled to a load through a transformer that has a center
A push-pull amplifier with exceptionally low second order distortion products is disclosed. The amplifier comprises a push-pull stage with a feedback loop which feeds back to the input any common mode
