1-07-2009 | Here we propose the use of two EL84 (6BQ5) power pentodes in triode SRPP configuration, without an output transformer The reasons for using...

1-06-2009 | There are plenty of designs for simple audio power amplifiers. These generally have a class-AB or class-B topology. Here we present a very c...

1-07-2008 | The reception quality achieved by ready-made DCF77 receiver boards tends to be proportional to their price. In areas of marginal reception (...

1-07-2008 | The distribution amplifier takes the composite video signal from a video player (VCR) or a video generator (analogue output) and buffers it...

1-05-2008 | Last month we discussed the principle of error correction and developed an error-correction power output stage. In this installment we will...

1-05-2008 | In Part I and part II about the paX amplifier we developed a complete error-correction power amplifier. In this accompanying article the pro...

1-04-2008 | Most solid state power amplifiers employ some form of global negative feedback to reduce non-linearities and output impedance. In some cases...

1-10-2007 | Valves (or ‘vacuum tubes’) are experiencing a real revival in the audio world, which can readily be seen from the large number of commercial...

1-09-2007 | You might think that amplifiers are like sand on the beach. But if you restrict your search for fully assembled amplifier modules to hi-fi a...

1-06-2007 | It is 100 years ago this year that the triode was invented by Lee de Forest.It is remarkable that triode output stages still occupy an impor...
