Adapted from something I saw on the web... I had to scratch my head until I understood C1: it bootstraps Q1's collector load (R2) impedance, turning it effectively into a current source. Gain is accordingly greatly increased. G = ~220 @ 40KHz. +3.3V --- | .-------+-------. | | 5K R1 C1 ...

What makes this amp justify its outrageous price tag, FFS? Is it due to it weighing in at 170 lbs per channel? Can it make the Sex Pistols sound like the Beach Boys or something? Where's the value here? http://tinyurl.com/jkkd2t4

What are some optocouplers you like that would be good for designs where they're used in unusual ways, like that "HV Opamp" thing JL likes where they're used as the "output stage" of an amplifier? Are any characteristics that I should look for in the datasheet that makes a particular coupler a better performer in an application where linearity is more important than high-speed switching...

So, I had a chance to get back to that calibration gizmo for my biochip front end amplifier (1 nA at the shot noise limit in a 100-MHz BW). It turns out that it's possible to do a very nice job, assuming that the integration cap (C1 in the schematic) has zero inductance, but as much as 0.05 nH blows it out of the water. (Should have thought of that, of course, but oh well.) Try running ...

Can anyone recommend a free software application for drawing a vaccum tube amplifier? I just need to show the symbols and wiring, not a simulation or cirucit board layout. Thank you, David King.

Greetings, gentlemen, This is the schematic of the CRO x-amplifier I've been investigating lately. It's supposed to provide sufficient potential difference to the x plates in the tube so as to sweep the electron beam left to right in accordance with the timebase setting: https://yandex.com/collections/card/5da36a58f05bf23ffde0742e/ At first I thought this was operating as some kind ...

Hi all, What is the best configuration for those first crucial one or two stages of an audio amplifier? I mean when you're dealing with the very low signal levels you typically get with phono cartridges (anyone remember them? - they're making a comeback!) in particular wrt to minimising noise and distortion? What's best for the front end? Are we talking long-tailed pair or something m...

Anyone have experience with lock-in amplifiers? I am thinking of purchasin= g a used one but don't know enough about them. I know they are extremely e= ffective at finding small signals buried in lots of noise but what are the = downsides to a lock-in besides expense? Also, this is probably over my head but I have read about the AD630 chip fr= om Analog Devices and supposedly that can be ...

Hi to all the terminally puzzled, --------------------------------- THE *problem* with the Crown DC300A is simple, but virtually unknown in the industry. Any amplifier that has response to DC is similarly questionable as being suitable or safe to use driving loudspeakers or transformers. Such amplifiers produce a large DC component when driven into clipping with an un
