100W Ultimate Fidelity Amplifier

[oscargolf]

FX8 is of course also good !
my project is currently AX-14
sounds good...

you can look at post 10363. Prasi posted the one he used for his layout.

This is not the same, you have balance pot in your no volume pot...

 

[prasi]

my current amp is fx-8 bimo mod with esp pre amp. sounds wonderful.

Your correct. I don't seem to have it. I will continue to look for it. Maybe Mile will see this and he could post it

Hello djbneben,
try AX-14 !!

fx8

And AX17 ? AX20 ? xD


There are many amplifier, but what is the difference between each ?

Hello to all,
I am also currently building the AX-14 power amplifier.
I'm still waiting for the circuit boards and then it will start soon.
My Peak Program Meter according to BBC standard is already in the starting blocks.
The PP meter consists of 80 light-emitting diodes with a dynamic range of -50 - +5 dB.
There are many circuits from the AX-14 here in the forum. Is there a final circuit diagram?
I am also looking for the Mosfet version.

Hello Oscargolf, the PPM circuit is your design? Can you share it? Thank you

 

[oscargolf]

Yes, I found the circuit years ago and had the circuit boards developed afterwards.
I still have two sets of circuit boards.
With printed circuit board etc.
The display board has a double structure.
One for bargraph LED or normal 3mm or 5mm LED.
I still have to look for the circuit.

OK, so I'm going to try these boards and see if it works as expected.

Regards

Just changed detection to PAMP transformer, i guess not too important since both transformer primaries will be directly in parallel.

hi me mile
about apex tb3 i want replace balance control with volume control...have pcb?

Was going to add this board to my order currently being processed but JLCPCB.

But they don't understand ur gerber version and file names

Hello all,

I asked previously what was the best amplifier I can build for 100w arround in 8R.

you told me AX-14or FX8..

On my side I want to use the components from my stock (new parts), and I have a ONKYO SR606 that I can desassemble too.

So I have :
- transformer from the ONKYO (2x60V after the bridge), maybe 300-500VA
- capacitors 10000µf
- Transistors 2SC5242 and 2SA1962 (2 pairs x 7)
- Drivers 2SA1930 and 2SC5171
- And all others components on the Onkyo, this AVR is working fine on the amplifier, but the HDMI board is totally dead.

So my question is what is the best schematic that I can use with these Transistors and Tranformer? Is there compatibility between yours projects and my "stock" ?

Are the gerbers posted for PSU15 - Looked through half of thread. I would order PCB's, along with PCB's for opamp pre and give the combination a try. I do have the opamp pre gerbers. Many Thanks!

go to youtube and learn how to convert gerber from your software that you have used to jlcpcb format.

I always order my pcbs from jlcpcb and never faced a problem. whats the nature of your problem?

PS
i understand that there is some problem with their online processing software.
attached are more traditional gerbers which should work well.

 

[Joel Wesseling]

Thanks prasi, happy to be ordering boards for psu-15, but got that mixed up with +15/-15. Is there gerbers for 2x24?
