OK Bro, sama2.
I've finished Protect speaker and it worked fine. I'm so glad for this. Thanks APEX
Mbokan wis genah layout e?
why? ... you can not use the basic scheme or drawing paths from the apex B500 series or H900?
you just change the bias section only.
for steper you can see on the H900, then adjust the TEF scheme that I send. 🙂

Hello Apexaudio
greetings can h900 driver stage be modified to 70 volts dc +/- to
get more power using TEF with 8 pairs its a wonderful amp

Driver stage on H900 work with +/-120V DC, only output stage work with /-60V DC and step to +/-120V DC in peaks.

Protect my second

Nice work, I suggest to warm up TIP31C to test high speed fan and thernal protect, also you can connect AC to PRO input and test overload protect (must be power off reset).

Oops.. my bad..I just happened to push the drivers with a bit more bass and the coils got toasted..😱. I also forgot that my traffo was over sized and did not use apex protect 😱.
Apexaudio or Andrew T or someone could please add a 50Hz low cut filter to the Amp input please .. It can be a little upgrade to the amp..

I've tried to use Solder TIP31C transistor to heat and measure the voltage coming out in the Fan and the result output Voltage grow up, but I have not found a way to determine the point of PRO (Short Protection) to work without having to use the Power Amp.

Hello Damanhuri,
Try to jump 1 of your AC line from protect AC supply to pro terminal that should deactivate the relay.
