2sb679 must s2sb649 sir

2sb679 must s2sb649 sir

you can use 2sb649 , no problems appear.

Hi Dear in the schematic, transistors Q12-13 are npn and they should be 2SD669.As it is in the PCB

 

[zaxos]

Ηi dear in the schematic there are two 1N4004 in the red psb there are two 1N4004 but in the green psb there are three 1N4004. please which one is correct?

No extra 1N4004 There is 1n4002 and the circuit is correct

Ηι guglusat Ιn the schematic there are two IN4004 but on the green PCB there is another IN4004 next to the 2SB679 transistor
why? also the transistors 12-13 are PNP and it must be in place Q9 Q10

Yes, I saw that there is no 1n4004 in the circuit, it needs to be removed

 

[zaxos]

thank you for the answer
with the difference that exists between the schematic and PCB with transistors 9-10 and 12-13 what do we do?
2sv649 are PNP and 2sd 669 are NPN
in the schematic it is a wrong position
I am an amateur and I want to build this schematic
has any amateur made this schematic?

2sv649 is false, true will be 2SB649 or 2SB679 , Also, the material is written in reverse in the circuit diagram. I haven't tried the circuit. circuit pnp with npn will replace the transistors.
Example from what I tested

300W Amfi Devresi

300W Amfi Devresi ayrıca hoparlör koruma devresi mevcuttur.

Follow the circuit diagram. There are errors in the correct material placement of the PCB.

Hi۔ Sir can we use 2SC5200 and 2SA1943 in the place of Power MOSFET Transistor۔

No, you cannot use it instead of mosfets.
