I was checking out the last few pages of the thread re: soldering techniques etc... and it occurred to me that in addition to the plethora of how-to info on perhaps Youtube specifically and the wealth of knowledge from members here... the following page might be generally useful for new builders to cherry pick the knowledge.
Now, this awesome website is really about tube amps for guitar—but at the bottom of this page is a full mini-discourse in soldering and component setup including some workstation tips...yes, it's geared towards turrets and bigger parts that tend to reside in guitar amps—but proper soldering techniques are covered and there's a lot of adaptable techniques for general wiring too.

Noted ! Do you really think it is the spade connections? I was hoping to keep it swap-able and modular...here are my notes from last night ( sorry for penmanship). Aside from that lead the rest of the amp was temp stable (using infrared thermometer) ...
I'm thinking mechanical (i.e Zem Mod) because of tapping stopping buz but...

lets take as example - industrial and professional equipment, which is having spade connectors inside ............ fact is that connectors used, are state of the art quality, no usual drek you can buy everywhere
meaning - both male and female connectors are made of bespoke materials (easiest recognized by hardness), and proper expensive (squeezzzz) tool is used for crimping
all in all, 95% of spade connector work shown around here is evidently of subpar quality, either because of drek hardware or that plus lack of mileage
recipe for disaster
and, to be sure and more efficient, all what regular greedy Boy needs is decent soldering iron station and soldering tips in few sizes
well besides having decent solder wire, it helps having some helper flux, for biggest and trickiest positions

result of misleading writings here ......... "oh, how nice and convenient are spade connectors!!!! superduper if ya wanna change summtin' in your amp trice a day!!!", while nobody is stressing importance of proper parts and proper technique, to Greenhorns
not Mighty Moi, Bubba ...... I hate anything resembling spade connectors
Here is tool and spades I am using, what do the "pros" use? Never had a problem with my crimping technique in the past. I get it that everyone is anti crimping, and I plan to solder everything when I get this fixed. The connector in question seem to be working well and drawing too much current, so I will be checking power supply connections and components today and see what's up... Thanks, T

If your wire is not the correct size for the female connector, the crimp is compromised.
Also, the connectors purchased on sites like Amazon use thin crappy metal that never securely holds….The Drek ZM is referring to, hehe.
Try these, you can rappel down a building side holding these female connectors crimped on wire.

Here is vid of tapping the chassis stopping the buzz for those that are interested in this saga... T
Hi. You need to read AND understand what the guys are telling you. You’re getting great advice and more than subtle hints to what’s wrong with the amp. As it is, the amps an outright fire hazard in my book. Connections getting brown/black from heat is dangerous, and you got it backwards. It is definitely not working well, and it is not drawing too much current. That bad crimp is creating a voltage drop and a lot of heat is being generated because of it.
Just because you didn’t make a mistake today, doesn’t mean you’re safe tomorrow.
It seems like you’re using the different color spades to color code the different types of wires. As is pointed out earlier, the colors on crimping connectors usually refers to the wire gauge they should be used with and using the wrong size is a bad idea.
I’m not out to get you or trying to be mean, quite the opposite in fact. I wish you all the best and want you to succeed and not get hurt. I’m being direct to get the point across.
Sincerely,
Lars.
nobody is acting mean
I'm still grateful and will always be to those rightful ones, caring enough to show me my errors and stupidity
it helped me through time to at least recognize when I'm stupid again
