Chào bạn Tôi tên Nguyễn Quang Tùng. tôi ở Việt Nam Tôi đã làm được 1 PCB D4K5 sau 3 ngày nghiên cứu mạch và nó đã hoạt động tốt uy lực mạch, tuy nhiên phần công suất có hơi nóng 1 chút, tản nhiệt tốt cho nó vấn ok, tôi đã tes với loa 8 ôm mắc song song.và loa đã cháy, chứng tỏ rất mạnh. Cảm ơn bạn đã chia sẻ PCB này, Chúc Bạn luôn mạch khỏe hạnh phúc

Nice to see a great DIYer! I've used the blue color paper transfer and I can see it gives me better details. It's preetty expensive so I will try this yellow ones you use for your projects these days. Thanks for all your wisdom you share to the world!

जिस पर प्रिंट किया उस पेपर का क्या नाम है

[sanjayaubesiri]

When i iron, some parts of toner still remains on paper without transferring to copper board. What could be the reason

[MultiTechChauhan]

can i print on photo paper with inkjet printer

[arunendrashekhar]

can we use laser printer to print pcb tranfer paper

[martinaudiosalem]

I try the TL494 500watt circuit it's so good

[bharathchandran.c]

is it working correctly? ??
how 4k5 ? calculation plz

[sandypadave]

4k5 amp make what list follow schematic or component?

[lakshithasamaranayake]

what kind of paper is used for printing

[linhleduy]

Hi. why IRFP250N die after 15 minutes. Can you help me?

[sandypadave]

Because component & schematic list deferent

[lambhuc]

Hi, where to buy that pcb transfer paper?

[durgasoundspayyanur]

good evening bro, bro how can measure MF if the lpf filter, bro pls tell the gauge, and how many turns, bro pls help me

[durgasoundspayyanur]

because push pull amplifier need more power transistors, its depending the out put watts, but, now i see class D amplifier but put stage some MOSFETs and a LPF filter, but its give 4kv put, bro how can handle Thea's heavy power D amps, and les heat it provide, how it possible bro, pls help me, u r my teacher, thanks, bro take care, sandeep

[durgasoundspayyanur]

brother, 1 question class D amplifier is powerful or a push pull amplifier
