Hi Apexaudio
greetings well i made your triac soft start my torridal has 13swg
in primary 11swg in secondary what must be the 50 ohms resistance wattage i am using TRIAC BTA41 40 amperes is it ok or should i replace with higher ampere triac
warm regards

BTA41 40 is ok, 50 ohms resistance must be 25W and you can use NTC for this soft-start also.

nice
What amplifier is this Sir..?

the transistor final only 2 pair right.?
hi everyone!!!...
today i've finished b500 and have mounted in the chasis...😛😛😛
i've tested it today...amp sounded reall good...very good for mids...
very crystal clear audio...very nice highs too...😀😀😀
one should make this amp...
tnx a lot to sir apex for sharing this very good sounding amp with us...
thank you sir...😛😉😀🙂
this amp deserves a drink...![]()







Dear Apex,
I am new here and i'm very interested to build this B500, please kindly forward me on
email address removed please PM
the Construction guide, PCB layout and parts list in PDF.
Many thanks for sharring this.

Yes, transistors, two pair. I want to remove this amp 200 watts, I used two pairs of output transistors only. If you need more then 200 watts can be done in the spring mounted on the output transistors.I have recieved but why can not open sir... have the pcb tested..?

PCB was made for ease of use in building an amplifier, all the output transistors through wires attached to the motherboard, it is very convenient when placing the amplifier in the body anywhere.

Yes Sir.. I like your system.. have you tested the pcb and how about the sound... can you send me the pcb layout in pdf file..? thanks
Please share the schematic Sir.. I think your pcb and component litle difrent compare with B500.. how about the max voltage for this amp..?
my apex B500
nice work sir 😀 Did you use Mje15033 and mje15032 or others ?

Yes mr Irwanks.. ..mje 15033 and mje 15032 easy to find in malaysia.... How in Bandar lampung easy to find overthere.? Next time if I back to Bandar lampung I want to make saound system project...nice work sir 😀 Did you use Mje15033 and mje15032 or others ?![]()
I hope you can help me and join together.. what do you think mr Irwank...?
