I still don't see a schematic.
Why don't you admit you don't have it or won't supply it
Quit jacking with us.
If you are going to sell amp kits, do it right.

Circuit often changes the changes.Can not be used as the correct design.
May refer to #5.
In the KIT, not with the document.

Let's see the correct design and do away with all the excuses.

Man!, you are dancing all around the right answer and solution.

I have a chassis with preamp and a PSU of +-DC 53V . I have only to decide for the power amplifier and protection circuitry.

What provides better sound, an Class A / B amplifier as the L7 or a classe D as the L15D?
If you prefer the class D, which is the difference between modules and the module L15DX2 L15D (other than being double)? Why the larger size of the L15DX2 caps ? Which is better?

L15DX2 higher than the L15D performance difference is not particularly large.

Distortion smaller.

Analog amplifier L7, its wide range of applications. No fixed rules on the voltage.

Are free to use, L7, very durable

Default Very good amp

I'm using L7 to play multi amplified system with peerless 830,452 units @100Hz xover. The bass is firm, strong, very pronounced. His power is 35 VDC. Does not heat. Very good. Congratulations LJM designer.

Default If anyone is interested...

I bought a couple of kits, reverse engineered the PCB and have created schematic. Should I publish here?

Can anyone tell me what is the sound quality of the L15D?

Normally the class D sound worse treble.

What would you advise me?, Build a class AB amplifier with mosfet or buy L15D Class D.

to amplify studio monitors.

Thank you.
