It’s a pity that you can’t easily quantify the changes in caps/resistors/ICs etc across amp designs. The level of noise of a resistor vs the dac 24th bit for example.
Fault finding triage and steps to return back to operation would be good. From the plug & fuse to the crystal oscilator.
Fully agree, but "nobody" will write a full article.
Being realistic, best I hope for is a few useful posts, each simple and focused, and quite practical minded, "hands on" as much as possible, no place for long articles on theory.
You answering to the wrong thread?
Ain´t all that way out of what a "noob" can handle?
Let´s keep it simple and practical.
How does one graduate from being a noob when there is no badge for that. It might seem unfriendly if the answer to a question is RTFS - read the fine sticky. If I try something I have not done before .. such as build a tube amp -- then I would be "tube noob". In other words, you cannot make progress without becoming a noob again.
That said, it seems I am wary of directing noobs to a side track.

I think there's two categories of noobs, not necessary exclusive:
1. those willing to build amps from scratch using a pcb and components
2. the modders/recappers/upgraders
They might have different needs and some common to avoid the magic smoke.

While the intention is good I can see this turning into something of a monument that nooobs don't read because it doesn't "immediately" answer their questions. Consider an alternative approach, "What's Your Problem", eg, Hum through speakers. Then you can ask the standard questions like 50/60 or 100/120Hz, both channels, increases with volume... Likewise with amp in protection. Maybe 4-6 actions under each fault heading. Certainly add basic info like service manuals and tools. Should also include basic biasing, ie, where to measure and transistor testing with MM... Just a thought...
This is something of a social and educational issue too. Noob status can apply to anyone from 8-80 yr olds. Whether you now need to go back to school or just refresh your Math and Physics before trying to read and report a meter reading or interpret an oscilloscope trace, is up to you, your test gear and whether you can provide satisfactory answers to questions that probe your credibility.
True - it doesn't confirm their bias forming their previously made decision. A diagram flow chart with tests could help direct/dissect that pre-formed decision but it would have to be split into amps, cdp, dacs etc to minimise the attention required. (we're dealing with the internet generation with the likes of TikTok attention spans through to people that can read Sartre Being and Nothingness for a bedtime read).
