Simple circuits don't necessarily mean worse circuits and NP attitude as an independent designer was towards his clients pleased ears...In the end if his clients are pleased with the sound it's all that matters to be successful and appreciated by a good hunch of people in audio.Better see his videos on his marketing aproach cause it's also direct and simple .
It's of no consequence if you're trying to sell perfectly linear amplifiers at 20khz to 40...70 years old people that can barely hear 10...12 khz..Give them the best musical experience that they CAN hear and you have them hooked.And be mindful that most rich clients are found in that age domain.
I consume a lot of streamed music tbh. Just a pair of good headphones make a huge difference even when paired with just a phone with a streaming app. And if you put aside systems designed especially to make loud booms there is nothing wrong with modern audio equipment like properly designed class D amps. I don't think numbers can lie.
The main reason I do this is my strange obsession with old fashioned technic. This is why I enjoy shooting and developing black and white films and even dry plates for example. It's like preserving a lost art. It's a kind of childish feeling. When you just came to this world you see things around you as permanent without any judgement and without any idea of their role and place in history, without the idea of progress and development. And of course without conception of the market. I grew up this way surrounded by pieces of material heritage of different eras which just existed. They existed before me therefore they are permanent. Transistor radios, cassette players and color films coexisted with books from 60s about vacuum tube circuitry and books about black and white photography dated from 50s to 80s. I just want to preserve this worldview.
Understand your fascination with old fashioned technical stuff. I regularly buy antique switching and measurement gear and these often are a work of art technically. They also work in most cases after a life cycle that should be over really. However they are made of various metals, good quality wood and real glass so they simply last. When I am busy with cleaning and maintaining such devices I look with one eye to stuff in my home that is made the last few years that won't be there in 2024.
I want my audio to be fully 2022 though but then made old fashioned with regards to mechanical quality. Class D, small, non obtrusive, frugal with energy and good sounding. Since it is a dying hobby anyway and snobbism is a big irritation factor in audio I decided for myself that good enough is good enough with a tendency to be over the upper limit of "good enough".

A 19 transistor amplifier is NOT "simple" under any circumstances.
To boot, you should have cleaned your schematic of unneeded (to say it politely) internal connectors (why would you need them anyway???)
I counted up to J18, and you didn´t even show a power supply or anything else.
That adds up to perceived complexity and clutters schematic and its comprehension.
You should minimally show a "finished" amp, not a tabletop jungle, offer a PCB design, show amp performance, etc. ; that is if we are talking about rising reader´s interest.
Hey, even pretty girls use makeup, choose good/trendy clothing, consider their hairdo, perfume, etc. before going to a Party .... maybe they have some experience about becoming interesting to others.
I took a peak at the project. 15 watts and lot of work. I can see that.
I'm not going to say to much about how it sounds. I hope it is wonderful.
You need to add a lot more thought into what others are seeing. That is a mess.
There is no reason for it to look like that. You used PC boards to clean up the wire runs.
Think about what you did and WHY you did it. You actually made it LOOK much worse
than it is.
You went backwards from a 20 watt planned output and then SETTLED for 15 watts?
The outside in not appealing.
Ok, that is honest feedback. I don't want to comment on the circuit design it's to complicated for me.
I don't like complicated at all. I'm old too. Look at some of the other DIY BUILDERS as a guide.
Do you think they want MORE stuff when it comes to 15 or 20 watts, when you can build a Pass design?
You may not see Pass as a hurdle. The Person isn't the designs ARE. They are simply GREAT.
In all honesty you are trying to make a round wheel rounder and wondering why people aren't getting to worked up.
Now refer back to my first post.
Chin up, Chest Back and take a shower you'll fell better.

I built a clone of the Pass "Blameless" amplifier out of salvage and leftover parts about 5 years ago. I did it to see how well it really worked. My intention was to build a scaled up permanent version if it worked out really well. The prototype was so good - unimpeachable I would say - that I'm still using it daily. I put it in an old chassis with a control/protection circuit (my design) and it never became fatiguing or showed any flaws whatsoever.
You can't argue with success. It's parsimonious, and excellent.

Not settled-settled but for heatsinks I happened to have on hands yes. At 20W it heat up to > 70ºC. At 15 it's about 60
Totally agree
I have some ideas. Except maybe turntables. Too much fine machining, I simply can't afford a workshop with all tools required
Here lies a big problem : you can't make everything at a high standard while every electronics guy I know thinks he can do it all alone...Very rarely technically minded guys make good bussinessmen.
Hold a design review meeting using one of the on line "go to meeting" services. Invite everyone you know to come sit and watch, as you go through each resistor, capacitor, diode, transistor - whatever comprises your circuit. You might even get feedback like;
"Uh, you cant have a capacitor connected directly across the CE junction of that transistor"
Just like we did it when I was in industry.
I'd use this kind of theoretical skills to review my designs instead of humans and leave photos of the actual products to produce some dopamine levels in enthusiasts living during the same days as yours:

Other than that, every passion on Earth needs financial feedback and support and electronics products in general are not art that outlasts generations...Van Gogh oil on canvas peintures last way more in a shed than electrolitic capacitors on the shelf...
If you want to make almost immortal electronics try passives and wind signal transformers ...They have a bigger chance of surviving the client than any electronics using electrolitics. By the way, a tube amplifier is better valued over time for a clear reason: it has very few capacitors to change , usually the high voltage longer lasting ones, and you can always change the tubes in less than 20 seconds...that's true design simplicity.

I'm barely happy if i can't enjoy whatever i do per se. Take for example bands, how many incredible musicians are arround there that can barely full a livingroom? its something always amassed me, how many pretty good unknown bands there are around every big city that u end up listening by chance. Maybe u r just depressed (world became an hologram, and us with it), and trying to fix that with a hobby (or whatever u call it) that's just supossed to make u have some fun, or some sort of personal growing, nor only wont do the trick, but will make the activity less enjoyable. Humans are inherently social, so its coherent that u get drepressed from no feedback. I say go get a beer with some friend below the sun, rant a while, get to ur home and see how amazed he is to hear sound comming from an amp u designed. Most of us, just dream that to be true... U r still 1 in 100k.
Validation is something you get sort of independet of what u do. U could get validation in some niche by selling lots of snake oil to "ignorant" people, or u could also pay for it (some master something somewhere), or u could do an ultra pretty design that everybody wants to build, like they want a pretty car. Its worthless. Nothing is permanent, we are certainly not, and even less, any validation or approval we may get along the line.
I saw ur thread and liked ur build, keep up the good work mate, dont try to fill something that's already full 🙂

Why didn't you name me instead? I would've enjoyed it for a while before someone else corrected you 🙂
