Wiring Diagram Driver Power Amplifier and Final Power Transistor
For this Yiroshi power amplifier project, I make a separate PCB driver with the final transistor, you can see on both picture PCB Layout above. The power amplifier is very good and high performance. You can upgrade again to add power amplifier by adding the final transistor and also replace it with more power, current, and stronger voltage. And also must be balanced with a larger power supply current and voltage. For more details see the full interesting video below:
This circuit have some problems after 4 to 5 min power transistor dead
ReplyDeleteno, please see at circuit diagram. There is no erorr, you must adjust bias voltage.
Deleteit can work normally not just a minute.
DeleteNice projekt and video! :D
ReplyDeletethanks dear...
DeleteGood amplifier and thanks for your video
ReplyDeletethank you, thanks for visit
DeleteThanks for video and project.
ReplyDeleteyoure wellcome, and say thanks for visit
Deletewe are happy to comment here, and we await your komantar in our blog
ReplyDeleteHello,
ReplyDeleteThe amp as shown in schematics will NOT work. Q15 should be NPN type, prrobably TIP3055, although I think this is a bad choice as TIP3055/TIP2955 have Vce max of only 70V.
Cheers
Q14=TIP2955/2SA1962
DeleteQ15=TIP3055/2SC5242
you can choose these transistor
the power amplifier is work, you can see the video testing amplifier
DeleteI saw some other videos the same circuit but there is no trimpot or bias circuit
ReplyDeleteyes, the circuit is no trimpot bias setting.
DeleteBut 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. Thanks a lot god bless..
ReplyDeletetry to use it cause the trimpot can adjust bias voltage if you using any finalt transistor type.
Deletewhat are the sizes of the PCB?
ReplyDeletesee pcb size on elcircuit stereo yiroshi
Deletehai i want pcb and components all so price please my email id: [email protected]
ReplyDeleteyou can contact me sir.
Deletehow to adjust the trimpot in the amplifier driver
ReplyDeleteyou can set output voltage until 0v.
DeleteHi sir romadhon, I'm back after building this power amp it sounds nice even though i tested it on 65v 8.5A so not enough power supply. Im Wondering on the pnp final output power they are warmer than the npn output i have noticed the predriver 2SA1837 for pnp output is warmer also is this normal? Because still sounds good or maybe i will get problems in the future. Please help
ReplyDeleteYou can change the emitter resistor by using 220R 1w. and also the npn transistor
Deletehi how are you can you tell me how to download the PDF, thanks
ReplyDeletethe pdf file is in stereo yiroshi amp post
DeleteSir can i use 90v symmetrical ?
ReplyDeleteyes im using 110V its normally. but you must have larger heatsink
DeleteSir what voltage should I use for 12pairs 5200/2943 transistor output?
ReplyDeleteyou can use up to 100v for more performance
DeleteCan I use IRFP240 and IRFP9240 for this project?
ReplyDeleteIt can't if you use final mosfet. see class d d4k5 its bigger power than this amp. if you want mosfet class d amp
Deletesir i am using with mjl21194,mjl21193 14 pair ? which use driver ..and volt ? ampere ?..
ReplyDeleteyou can use this driver or yamaha PA-2400, 80 upto 100V is recomended try using 20A current transformer ar SMPS circuit.
DeleteThank you sir
ReplyDeleteNice amp sir but sir you use cliping indictor and protection ckt
ReplyDeleteIf i use 8 transistor instead of 14 transistor in the final driver Will the amplifier still work?
ReplyDeletewhat current rating should the L1 coil be
ReplyDeletemax 20A output
DeleteIs it possible to send me better quality PCB, and PCB size, and layout files, also schematic diagram please [email protected]
ReplyDeletesee newest post sir
Deletesee newest post sir
