I see this in several of these build videos. You must have a good mechanical connection whenever you are attaching or connecting things together. Solder is to connect things electrically. It can get brittle and break with age, especially if things move around. It is work hardened very easily. What you see here might be good enough for testing an idea but anything permanent needs to be mechanically connected first, then soldered. And yes I am aware that modern machine placed components on circuit boards are often held in place by nothing but solder. Those work fine for tiny resisters and such that weigh nothing. Wiring and such needs good connections to last.
That amplifier is so wrong, you need the VBE Multiplier transistor on the outputs heat sink or it will self destruct by thermal runaway, on top of that there is not fuse for the toroid primary, when the outputs get destructed the short will make that toroid a ball of fire.
I am definitely going to build one of these, with a pre-assembled rectifier & pre-amp board though. I am amazed at how cheap most of these parts are, minus the toroid. EXTREMELY CURIOUS at how well this thing will sound on expensive speakers!!
Thats an awesome video, but I was waiting for the music test of 1000W or sinewave test to show 1000W, oh yeah. Its not there, can you make part 2? Or maybe I will make one.

I really like your clips. Follow every clip. I'm from Thailand Knowledgeable I like electronics.

Que maravillosa es la electrónica..más si la comparten y sus muchas maneras de adaptarse..gracias y muchas felicidadez

After this much hard work, video ended as if the creator was gonna miss the bus
Love the unedited soldering Going to build this one
Muy bueno eh aprendido de este proyecto, Jorge Quintana desde turbana bolivar
why do that entire build and then stop the video before testing and showing how good it works!
the powersupply needs a centre tap from the transformer othervise it would not work well
Donde consigo esas placas para los transistores tendrás alguna página de internet donde se puedan comprar?
Saving this vid. Planning to follow your build guide.
this is a VERY serious realisation ! congratulations !!!
Nice assemble..
good idea thanks you very much
50 watts, no more from that transformer.

Nice love this channel
