A Zener diode is a regular diode too.
There is no need to add a 1N4148 at a ZY7V5.
The 1N4148's are back to back to the zeners. The upper one switches the zener off during the negative half of the Signal, and vice versa. If they weren't in place, the driving voltage swings were limited by the zeners' forward voltages.
Best regards!
Yes, you are right, I was wrong, the 1N4148's do have a purpose.The 1N4148's are back to back to the zeners. The upper one switches the zener off during the negative half of the Signal, and vice versa. If they weren't in place, the driving voltage swings were limited by the zeners' forward voltages.

Hi mile i want to make nx12 and i want to now how much power have nx12 +-60v 8r and 4r . Thanks!
100W/8R, 180W/4R
It's time to post the diy friendly format.Replaced zeners with correct value and added 1N4148 on layout.
Revised NX12 layout using final schematic from post #9731.
P.S. I deleted last post because of error in layout.
Hy sonal can you post the .lay file for nx12 ?
While sonal doesn't upload the official pcb layout, pdf version, for NX-12, I made a draft using some image processing software.hi sonal great work. please post the pcb pdf for the nx 12.
*** ATTENTION *** Please check board's actual size and possible mistakes before etching.

Sprint and pdf files for NX12.
I have made two NX14 few years back and used them for subwoofer. I'll be making 2 pair version of NX12 layout and test.

thanks smart and sonal GOD bless you.
is the sound quality of nx12 good to be used for mids ?? can i use irfp460 instead of irfp250??

Greetings to all, especially Mr. Mile, is my first post in this forum, I dare to ask Mr. Mile, which amplifiers or amplifier recommends me to use them for subwoofer?
What is subwoofer specifications?
Use BX22 from post #8181
