100W Ultimate Fidelity Amplifier

Next amplifier

Hi at all,
after finishing the Quasi amplifier for beginners i started as new project the AX14. Here the first picture from PCB for the prototype.
First amplifier was confiscated by my son, so i have to build a new one ;-)

@vargasmongo3435, that amplifier you're talking about has been built by @44250 himself! Somewhere in between Mr. Aleksandar called it A100, but it seems to be D14 with darlington outputs, what seems to be a previous version of AX-14, the main goal in this thread.
Hope this helps.😎

Sory,that is the one that has a few names (D14/AX100) and i have remembered it by the D14 name. I haven´t built that one but i did similar-AX12/B80. That one (D14/A100) was built by the ElektronicarPG and it has given him abot 171 W at +/-60Vdc supply at 8R non-reactive resistance,without visible distortion od output signal. The supply voltage should be smaller than +/-60Vdc but even than there would be plenty of power at the output.

Sorry for the offtopic...
 
this is my AX14P (with protector), i like the bass so deep and tight

Nice pcb, I suggest to add protect from AX14P instead LED indicators.

I'm confuse to be honest

Hello guys a I have to stop for a moment because I copied this layout and the LED indicator got me really confuse, mister Apex suggest it to use AX14P circuit protection so has some one already build this layout with the LED indicator before? I mark some areas that I'm not sure or in other words confuse 😕 I don't want it to mess it up bad, any help? I'm like this character."😱" lol

Hello mister Apex!, did some one build it with this LED indicators? that is why I have to stop, I can replace them with the relay protection and is someone want to build it with the LED indicators I can have two layout versions you think is a good idea? 🙂

Hello Juan,

Can you share PCB Layout.....

Also please make vertical position on those output tranies i will try to etch your pcb design...

Wiljj78 😀 I send you the files by e-mail, I also send you the Sprint Layout 5 file in case you want it to open it and make any corrections, if you can't just mark it with paint program ans send it to me and I can fixed, really appreciated dude.
