Guys let me know if you found any error.

Greetings mister whether these protectors can also be used to ax 17

thank you

Let's hear the answer from Mr. Mile about this question.

Lets get confirmation from Mile, but this protection should be generic for any amplifier.
Some component values might need to change,

This protect is a great share.
Thanks Mile

This PSU with protect can be use for any amplifier, just change 680R/2W resistor to get 24V on relay or 12V for lower rail voltage and 12V reley.

thank you sir Mile who have shared her design and host wiljj78 very helpful for people like me who want to make the power amp

This simple shunt regulator can be use with AX amplifiers for preamp supply. Amp rail voltage can be use for regulator input (without 1N4007 diodes and 4700uF caps).

I've played a bit. A small heatsink connected with thermal adhesive (more for peace of mind;-). Some photos for 20kHz, 10kHz and 1 kHz with signal generator until 30V peak to peak at output. Load resistance and heatsink are good warm (too small).
In each perspective the amplifier operates stable and has a warm and transparent sound.
It is a very nice, cool amplifier - typical apex.
It's fun to build it and you get an impressive sound.

Thanks again to Apex.

I do not know if I am asking for too much but can You repeat one square wave measurement on 8 r with small cap in parallel please ( someting like 0,47uf or similar)

Thanks

Yes, no problem, but not before next week - because i am not at home this weekend.
