This one is good, but need to rebiasedSometime there is small distortion thats why. I mean which pins of the circuit? It's not clear in the video. Hi Mr Eko, Does can i get the printed pbc to this particular amplifier diagram? Thank You Where I have to connect 2 n 2 75v capacitor under the pcb of final transistors?
I wish I could get sprint design full version or design spark full version even if it a cracking version. I need these montages, what are your conditions? Thank you, Yvon. I would like to learn about your drawings, it is w w,w, w, and what have you already test these montages? Layout Pcb Yiroshi Mk7 For the final transistor, on this yiroshi stereo amplifier project, I do not use transistor Toshiba 2sc and 2sa as well as sanken transistor 2sc and 2sa Thanks a lot. Later you will be able to see the location and position of the transistor, after the power amplifier is finished and ready to be produced. I have also tested it in the unboxed state of the box, using only 2SC and 2SA final transistors, this amplifier is capable of high enough power until my speakers are damaged and also my smps is damaged This power amplifier is tough enough, none of my final transistors parallels broken.īecause the previous transistor has only a maximum voltage of 60Volt with a maximum current of 15Ampere, so it is advisable to use a larger transistor maximum voltage and current. What can i do for it? Important for a blogger to have a reference Take for example, I like a blogger on this site.īagi banyak wanita, mengakhiri kehamilan adalah keputusan yang sulit.Power amplifier yiroshi is suitable for outdoor or indoor. I make w mono amplifire using this driverboard. I am very interested after reading your article. A very good article and very easy to understand. Thank You Very much!!!!! Explain the guage of wire and how many turns wanted cara menggugurkan hamil.
Sir it working but humming problems and transistors hitting very quickly Please solve the problem sir.
How to make the 10 uh coil bro Explain the guage of wire and how many turns wanted. Hi sir i just need to ask where to adjust dc offset of this amp i need to adjust to 0V dc there's only one trimpot but adjust only for the current bias. Hola disen que ay que cambiar 2 resistensias las lateralrs de 4k7 por 47k. Hey ' i need purchase this amplifier subwoofer kit Yes after I corrected the errors on PCB layout, and found a schematic that was correct, have sold over so far, I also have the Crown XLS 6 fet as well, with corrected schematic and PCB, only sold of the so far. Sir can i use in the circuit 10 pairs of final transistors then the speaker out is? Watts and Witch transformer I can use please tell me sir. I want to buy all the components of this amplifier.
If i use 8 transistor instead of 14 transistor in the final driver Will the amplifier still work? Puedes pasar el pdf y las medidas exactas de la placa en que parte del diagrama va el trimpot. You can change the emitter resistor by using R 1w. Im Wondering on the pnp final output power they are warmer than the npn output i have noticed the predriver 2SA for pnp output is warmer also is this normal?īecause still sounds good or maybe i will get problems in the future. Hi sir romadhon, I'm back after building this power amp it sounds nice even though i tested it on 65v 8. But on the assembling video i saw there is bias tripot I'm confused, but anyway thanks a lot for sharing this powerful amp i will try to build very soon. I saw some other videos the same circuit but there is no trimpot or bias circuit. Hello, The amp as shown in schematics will NOT work. There is no erorr, you must adjust bias voltage. And also must be balanced with a larger power supply current and voltage.
You can upgrade again to add power amplifier by adding the final transistor and also replace it with more power, current, and stronger voltage. The power amplifier is very good and high performance.
