    Yes it is. Designing what you suggested is literally something every electrical engineer needs to do as part of their degree, often it's a simple second year course before you get into the complicated nature of switching characteristics (such as class-D amplifiers) that are reserved for advanced parts of the degree.

    You're confusing a bunch of things. It's easy to design a class A amplifier of some sort. The entire topic of the conversation is about high quality audio power amplifiers. A BJT a and a couple of resistors make a class A amp. It is not however simple or easy to design a high quality audio amplifier like that.

    It's laughable that you think that because switching can be complex and reserved for the later part of a degree that it's complex to use. Many people can buy an arduino and a motor shiled of some sort and drive motors at variable speeds. You don't need to be in an EE degree to do that.

    Let me reiterate since you missed it first time: to make a class D audio amp, you buy a class D audio amp chip, and stick it to a board. Wire up the output pins to your speakers. Wire the input pins to your audio source. Wire up the power supply to the power supply. Scatter passives around according to the datasheet. Done.

    Maybe an Atmel chip of some sort if you want to poke at the I2C bus. Maybe not. Depends on the chip you buy.

    Oh I agree. But I'm not sure you know the heritage or what the "Linear" part of Linear semiconductors actually refers to.

    Completely irrelevant.

    Doing a heatsink calculation is easier than solving ohms law, but then your original requirement didn't say I wasn't allowed to use heatsinks, that's moving the goalposts.

    YOU said it was simple, so I'm not moving the goalposts. Now you're saying you need to do faffing with heatsinks and calculations with them and you say that's easier that shoving a COTS class D chip on a board? A 30W class D AMP will dissipate less than 2 Watts at most, little enough that you can simply sink it into the board. With a class A you're looking at sinking maybe 90W which is much less trivial.

    So sure you can use a heatsink, neither of us claimed it was out of the question but do not deny that using one is harder than not doing so.

    You've done it wrong.

    I guess it isn't easy then! Easy means little room to make it wrong. You can shift 90W without fans but that's getting into a non trivial design. We could pick a different part of the power envelope if you prefer.

    You didn't design a class-D amplifier. You bought one off the shelf. You can do the same with with any other.

    Whoever said from scratch? Now you're moving the goalposts. We were talking about products not some idealised design exercise, the products in question being audio amplifiers. You don't make a product, especially a low cost one, these days by designing everything completely from scratch.

    If you're going to build and sell an audio amp, chances are you'll pick a class D chip off the shelf and slap it on a board. Depending on the chip, that will give you anything form decent performance to actually really good performance and likely very much better than anything at even 5x the prrice from before really good, cheap class D chips came off the lines.

    Just buy a small Coretx-M0 with an I2S bus and bitbang the PWM or sigma-delta directly and hook 5 GPIOs to 4 power MOSFETS.

    No, old man, no it's not. But it's what you might do if you wanted to do it by hand rather than simply get a chip like a normal engineer.

    See easy! Just because you don't know how to do something doesn't mean it isn't trivial.

    Quite. You don't realise how easy it is, so you assume it's hard because you don't understand it. A lot of perfectly good electrical engineering these days is coupling together digital blocks on an I2C or SPI bus. It lacks a certain something perhaps, but the parts ar of amazing spec and it's really fast to design not to mention cheap to make.

    Well I guess it depends how cheap is cheap and how midrange is midrange. You can get something much, much cheaper now wich will easily perform as well.

    No it's really easy.

    No it's really not.

    Compared to a class D amplifier it is incredibly trivial by comparison.

    What? No. You can buy Class D chips off the shelf. To "design2 a class D amp, you slap one on the board. You don't have to worry about PSR because it does that. You don't even have to worry about the signal level analog stuff because it's digital in. Pick one to match thee specs. The folks at Texas and Linear and a bunch of Chinese manufacturers actually know their stuff pretty well.

    There's no need to do faffrey with heatsinks, low noise fans, analog signal levels, noise floors and etc. Someone has already done all that hard work and put it in a chip. You don't need to make a high power low ripple PSU because you're drawing less power and the chips do supply rejection for you.

    Excluding the PSU, it's one chip and a few passives. It doesn't get much easier.

    And if you really wanted to make one yourself? Just buy a small Coretx-M0 with an I2S bus and bitbang the PWM or sigma-delta directly and hook 5 GPIOs to 4 power MOSFETS. DPAK and a nice ground plane will suffice for thermals. Modern MOSFETS are fucking incredible.

    You know that the electrodes in tubes get contaminated and evaporate, right? And no two tubes respond exactly the same.

    No two FETs respond the same, either. The closest you get is the matched pair discretes you get on the input stages of high end measurement equipment. The good amplifiers all used a high gain configuration with negative feedback so the response is as linear as you can get.

    It is possible that the nonlinearities sound good to your ears, or you have a whole lot of unintended low pass filtering built into your tube amp, plus some unintended resonances, and you kind of like the modified product.

    Several problem with that. Plenty of academics turn down peer review requests from lower impact or unproven journals. Not because they're snobs but because the peer review system is massively overloaded and few people have the time to review everything that crosses their desk, so you've got to filter somehow.

    Secondly those journals will have trouble attracting the good papers in the first place.

    They will also have trouble attracting readers (and so citations) as well, what with being lesser known in the area. That feeds back into not being able to attract the best papers.
