Oh the sound is great clear sound and no hum at all but i had to use preamp with tone control due to my diy two way speaker because they came a little bit crispy in high !! I think that is a good amp to build and listent any kind of music.Thanks Mr Apex for sharing !!
Thanks you for building this amp.
Hi guys...
This is my Christmas's Tree edition
Merry Christmas & Happy New Year
Thanks to Mr Mile, for sharing very much project
We always wish all the best for you
Regards
GBU & peace
Thanks, what is this amp on the picture?
Regards
AX20 "S" with 3 pairs output

This is AX-20 with 3 pairs output & symmetric pcb layout but not tested yet

OC detect
Hi everybody,
Let me wish you all a very happy new year!
I built the OC detect and I want to protect my NX-14. Should I need to change any of these components if I want to work my NX-14 with 2 ohms speakers.
I would like to know how it works, so I can change the components and post my experiments.
Power supply 40-0-40 DCV
Emitter Resistor 0.22R/5W
PS. DC protect with NE555 works fine! Thanks dear Mile for the circuit!

This one will be used at my old school
And BC550 & BC560 should be OK, right?
I use BC550-560 on this AX20
Sound is great, it has been sing for a while now.
I had a distorted sound at high volume, but I realize that I don't adjust bias yet
So I adjust the bias, the 1k resistor must be increased.
Now it sound very good, very clear & powerful sound.
This amp will be used in the school that I was there long time ago.
I build it for my teacher there in the school & He and all the students there must be like the sound
Maybe someday many of them will studying how to make a great amplifier from Apexaudio
Thanks for sharing, more happy people out there

Hi John and happy new year to all of us
Is this pcb for sharing?
Best regards.
