1000W Simple PA Amplifier

[pose pro elc]

Okay, when compared with the apex H900 with voltage 120VAC 60 & BA 1200 .. with apex 60VAC bridge mode .. thanks in advance ..

Is that the feedback tapping on the opposite end from the speaker output tapping?

sounds like you do not read what is posted to you

There is some mistakes on your pcb.

when it comes to his own designs, Mile have a very sharp eye

The narrow tracks for the PSU. It will burn.

pin bolts mounted in heatsinks
and they make it difficult to get bridge and 1. smoothing caps mounted

 

[tinitus]

but not impossible
somehow I knew something like this might happen

Did I read it right Mr.Mile that somewhere here in the post that you made actually
a 5 pair output?..How many volts that you made it?

Amp can use different rail voltage and numbers of outputs:
+/-40V................1 pair 100W/4R
+/-50V................2 pairs 150W/4R
+/-60V................3 pairs 200W/4R
+/-70V................4 pairs 250W/4R
+/-75V................5 pairs 300W/4R
+/-80V................6 pairs 400W/4R
+/-90V................7 pairs 550W/4R
+/-100V..............8 pairs 700W/4R
+/-110V..............9 pairs 900W/4R

These performance data are much more than conservative... +/- 110 are over than 1.2-1.3 KW @ 4 ohm
