500W PA amplifier with Limiter

[ihsanmansor]

Hi everyone, This is my first posting and just for sharing. I built this project on project board because easy for me to do some tweaking and just for curiosity..I am only a hobyist and audio amp enthusiasm. Built base on B500 design and using those component that available in my rack. I learn many things in this forum. Many thanks to all especially to Mr Apex.

and signal indicator in this forum??

 

[gantex]

Yes it is, B600 use buffer inverter on amp input

sir soerdjanto can you share apex b600 with balance
input, peak indicator
and signal indicator in this forum??

i dont think mr.soerjanto will share his project. I dont know why and how. I follow mr.soerjanto in this forum, and no shared from mr.soerjanto. Perhaps i think because he is a sponsor indo forum. So i read if want something from mr.soerjanto just go to indo forum and upgrade member, so u can download any attachment. Anyway its for diyers but, special diyers not free diyers.

Regard.

hi andrewlebon,

is that red line in the middle of the board (top) a missing trace in the copper board (bottom)?

edit: i see now, it is a jumper.
