100W Ultimate Fidelity Amplifier

Juan,sorry but i feel that this pcb is on the wrong way!🙁
I thing that you has built a nice AX14 pcb in the past.
Prasi's AX14 pcb(post#10380) is a good example!

Nice little PCBs from PCBway ! also look at what a nice little free gift PCBWAY included in exchange for some accumulated coupons. It gives a very good visual perception of different devices and trace widths, which is not so apparent during PCB designing. Being loyal to boardhouses has its advantages😀.

Hope to build this during rainy season. Has anyone used MJE150XX devices for drivers?

Can we get here gerber files? Thanks

I understand thimios but I feel bad to ask for gerber files I know how hard is to design from scratch, the first version of the AX-14 is nice but I want to try something different yes it might not be the best layout but at least I try my own way the best I can 🙂



Best Regards
Juan

You're welcome to my version. Note that I don't have fuses on the amplifier pcb. I have my fuses on the power supply. The board is quite small this way.
See gerber files attached.

I have it shared here. You may download gerbers.

Thanks prasi, i downloaded gerber files, import into sprint layout and it looks very professional made..thanks for sharing gerber files for this nice amplifier.

Hello!! Is it possible to put the resistors in the amplifier 0.1 OM instead of 0.33 ohms? APEX AX-14

I'm not an expert but try 0.22 ohm a 0.1 ohm might give you problems at the moments of reading bias adjustment

Thank you, then I will not take chances

Thank you, then I will not take chances

you ca go with this values too 0.33 up to 0.47 ohms 🙂

Stereo AX-14 2 pairs for clarity and AX-20 5 pairs for bass...

Hello willy, its about post #3381. Its really nice work. Nicely arrange in cabinet. Plz share AX-20 5 pairs PDF file or sprint layout.

Hello.I am planning to build this series PSU but for +-18V output.I will change the 24V zeners to 18V ones.Will a 2X18V AC transformer be ok or should i use 2x24V AC?

hello maouna,
I had the same question earlier, Mr. Mile recommended to use 24VAC. I will try to find the post, as it was a long time ago.
