apex transistor protect issue
hi apex sir ,this protect not suitable for h900 at 45 v ac rms relay automatic off then on please tell me how to modify this protect circuit but dc sense is very good.i made four all have same problems. plz tell me how to fix.thanks.

hi, guys.
I have a question.
please answer me anyone.
I have two amplifier
1)2 nos apex b500 rail voltage is +55 0 -55v DC.playing in bridge mode in 4 ohms load.
2) 1 nos apex H900 rail voltage ia +110 +55 0 -55 -110 DC . playing in 4 ohms load .
so what is the difference between
1) audio quality ,bass response.
2) stability

Hi sir,rohin
this apex discrete stepper is not working properly,negative side suddenly increased rail
I think you put wrong resistor on negative side. 22k must be replace with 2k2 and 12k instead 1k2.

hello sir apex,does the ckt prevent volt/current loses or dropping.thanks
Hello every body
Please tell me that nsl dot point is anode or cathode.Thanking you.
Dot is the anode lead.
Why does the signal gnd and power supply gnd separate?
that reduces hum at the output,preventing dividing gnd current flow through input cables. leave it as it is.
