Hi.
this is a stereo apex ax-14P that I've made recently.
It has very clear sound.
I've made very amp heretofore, but this one is one of the greatest amp that I've ever made.
but when amp clipping occurs, the relay goes to Continuous off/on that destroys the sound.


Best Regards.

Nice work, what is rail voltage and what is voltage on relay coil?

Hi.
PCB was Ok.
the cause of the problem was transformer voltage drop. I fixed it by replacing transformer with another one. Now everything is Ok.
I connected a 5-Band equalizer with M5226p (Mitsubishi) to Ax-14 and the sound quality is very nice.
the sound has clear treble and tight bass.
actually Ax-14 is better than many commercial audio systems.
regards.

Hi Mile,

I am building and amp and Preamp for my son. The pre will be the P30 and the amp witll be either the A33 or the A40. I would like to include the APEX logo on the front if that is OK with you. This is a gift to my son and will not be sold. I just want to give you the glory for your design. Please let me know if this is OK with you.

Thanks, Terry

It is OK, no need to ask.

That's a nice gesture Terry... I hope I can do that too for my daughter (when she gets old enough!). Do share the pics and description of the build and its 'your expert' review. I might try it...

Hi Mile,

A question for you. As you know I have built most of the amps in this thread. As I mentioned I am putting together a new chassis for my son. I have both the A33 and the A40. The PSU I am planning to use it +-62VDC. Which of those two amps do you suggest? Another choice would be the FX100 with 3 pair of outputs. I want to give him the best APEX amp I can.

Thanks, Terry

Thank you

My vote is to A40.

A40 and P30 is the best APEX.

With 70 actives between them they should be the BEST. I should build the A40 someday.

Link to A40?

Does anyone have an actual power supply circuit with soft start and high frequency filtering on the Supply rails?

Probably.

 

[stuartmp]

I have a few circuit diagrams but none showing soft start while incorporating high frequency line filtering of the high frequency generated by the bridge retifier etc. I really appreciate a working scamatic so I can put one together and start building some audio amplfiers.
