Quite similar to the work I had been doing when it came to solid state amplifier repair except the STKs were available (1972 to around 2000). I got so experienced with transistor amps that I even made some from scratch in the late 1970s early 1980s. They still work now, trouble free.

Buen día saludos para stk 040 que transitor se puede usar
@DanielImmanuel21433 жыл бұрын
This may be possible....BUT, STK's were designed with overload protection, thermal shutdown and bootstrap features. Akai designed circuits around available semiconductor devices at the time. This is a dire straits situation if no STK's are available then yes. Sound characteristics may differ since transistor hfe are not exactly the same. Unless STK specify equivalent transistor circuits.

Hello my friend, you are brilliant at this work. Thank you for this information. It was very useful to him Item 0040 It has been unemployed for a long time, and my question is, when the transistor is replaced with 2, it still has the same power. Should I leave the middle connections permanently? Thank you very much, Your Honor.

It would have been nice if you could have focused on the npn that's would be able to tell which one you were using but obviously you were going too fast and if you really didn't consider that other people might want to know
@javierfernandez18084 жыл бұрын
STK0039 es cuasicomplementario, lleva 2 transistores NPN, y el STK0040 es complementario, lleva un NPN y un PNP, además esos son darlington, el A1943 y el C5200 no lo son, necesita transistores drivers, falta el ajuste de bias también.

Because this person does not know what the hell they are doing. it seems to me like this is the type of person that claims to be an engineer, by reading the the first chapter of an electrical engineering textbook. Or as if taking only the first year of schooling to become an engineer and nothing more. It seems they have a very basic knowledge of the engineering of electronics but nothing more. because there is several simple and some quite drastic mistakes that this person makes in several videos if not all of them. if you wonder why they don't talk this is why because they don't have any knowledge in the subject but just a very rudimentary introduction to this field of engineering. save yourself some time and effort and heartbreak and don't attempt to rebuild the this channels work I have yet to see one that is correctly done from A to z

But just yesterday, accidentally I plugged it to 110v source(normal 220v) and it worked, of course there is a buzz sound coming out it(I guess that's because of low power), on 220v it's still not working. What could possibly have gone wrong?
