from where did you sourced C3 3.3 uF input coupling cap. and should we use bipolar electrolytic cap (C4) instead of regular cap. Can we use COG SMD 47 pF ceramic cap instead of thru hole cap?
1. The WIMA caps (C3) I recently sourced from local market SP ROAD in Bangalore 2. Yes bipolar caps can be used in C4 3. Yes COG caps would be a great choice . Best would be Silver Mica (but its pretty costly).
I do have 4 of these boards left (empty pcb)… But I would really recommend you to get the gerber files of the new design … since this design is having one silk screen and one pitch related flaw.
Is there any difference in sound quality with zobel network ( Ultimax board ) and without zobel network ( your PCB ) . Anyway Great effort 👍 keep it up 👍
Thank you so much ☺️ 1. Im having zobel network in my PCB . I think you mean Thiele Network. If you are asking about Thiele Network then I have not included that inside the PCB but I have it connected as an external component. If you see during sound test I have that coil connected between the output and the woofer. 2.Thiele Network is a must component for LM3886 …. Or else it would sound very unstable and uneasy under various scenarios.
@@rajeeshraman9982 It is 100% original ic buddy … Fake ones dosent have short circuit protection or thermal shutdown . Neither they can produce 50 plus watts .
Great work! 🎉
Thank you 🤩 🙏

can you sell one of these boards?

This fake ic not original

@Roys_Desk no original ic
It is 💯 original IC Lm3886T/NOBE
