Given, the use of multi-caps in production amps and electronics is a result of their economic efficiency. You're building your own amp - the economy in that is already compromised, why not shelve those unfounded entrenched ideas and go for an alternative that is of no disadvantage and potentially of some in your personal creation?
As per my previous suggestion, this:
even a reduction in the amount of noise due to the fact they suggest that lead dress can be improved due to a less cramped chassis interior.
is largely irrelevant.
The PT story is something unworkable regardless of your layout, you have what you have.
Just to clarify something. I'm not building my "own amp". I'm building a Trainwreck Express clone with a couple of practical changes to make it more suitable for my purposes. In fact, the term "building" is even debatable. It's probably more just assembling in my case, rather than building, although I'm not building from a kit with instructions.
I get what you're saying, but at the same time I think it's important to note the contraints within which I am undertaking this project:
1.) I'm on a limited budget.
2.) I will be building this amp on my study desk. I have only the basic tools I need for assembly. I don't have the means, whether its a proper place to work, nor the necessary tools to customise or fabricate anything.
3.) I'm a beginner and so my knowledge and expertise is extremely limited, and as such I feel and get a certain level of comfort from starting with a
known base configuration. Those "entrenched ideas" allow me to at least get to a point of something that is largely known to work and produce a certain result. It also means I will be able to find support and assistance out there should I need it from a larger pool of other builders, should I need it. If I decide to do something unconventional at this stage, I'm on my own, and others would find it difficult to replicate a problem I may have. Once I have a stable base configuration in place, then from there I can experiment and try different things but at least I can then always go back to my base if it doesn't work.
4.) The Trainwreck Express is a notoriously difficult amp to get running well. The easy part is the actual build. From there on, it's tweak tweak tweak until you can get it to work reliably without oscilating, howling, hissing, farting and god knows what else. Bottom line, I'm already probably biting off more than I can chew here building the "Standard" amp, before I start down a road of including any design changes.
This build, and likely even the next one will in all likelihood be clones of existing amp circuits and layouts. As I get more comfortable and confident, so will I mod and tweak more, as well as try my own ideas out and start breaking away from those entrenched ideas. At the moment I don't have any ideas because I have too little experience to base them on. It's a process, and I need to crawl before I can run.
Does that make sense?
