500W PA amplifier with Limiter

[sajti]

B500 tef 8 pairs
Sir mile iwant to build B500 TEF 8 PAIRS Sir this layout is ok sir? thank you so much sir Mile Advance merry x mas sir..

Not really good. The rails, and the output tracks are not wide enough to take the current.

he is author of b500 but not that pcb.you have to ask from that man who made that pcb. pcb is not good and issue of protect circuit too.may be work but no one can say 100%.as diy i suggest you make b500 with apex pcb and use njw series.using more transistor never mean you got much power.b500 powerful with 4 pair.this is my view you can do as you wish.

Hi Mister Mile, I would like to hear an opinion from you, about B2000 PCB that I did, theoretically all electronic components are well conected (I hope🙂), I put some decople condensers to. I would like to know, if I should put heat sinks in red and blue transistors, on VAS PCB.

Thanks in advance

Happy new year

Yes that transistors need heatsinks and BD139 must be on main heatsink... BC639/640 wrong pins... this amp B2000 is from thread: http://www.diyaudio.com/forums/solid-state/235892-1000w-simple-pa-amplifier-65.html

hi all which posts #?? shows the thd measurement of this amp??

 

[ArDean]

I hope that nobody go to build this amp as his first amp ever. Some expirience is welcome, and can help with first powered.

just wait for me ,i already get the b500 pcb and put the componnet just for 1x 24h i will share the result😀 (newbe)

Hello everybody! I did B500, it works, but it does not play cleanly in a small volume. But with an increase in volume plays perfectly. What to check?

all of you solders is good? And check the input capacitor too.
To my old amp that problem it was from input capacitor, was leaking.
