Amplifier motherboard

[QQ12e5k1]

PCB

are tou finish to testing??
when will you share your pcb sir?

regards

This amplifier module named Kelvin is made for testing driver circuit. There is no VI limiter just fast fuses. Work with +/-56V DC PS.

What changes should be done with this circuit to drive o/p transistors like 2sa1943/c5200 or non-darlingtons ?

Very nice, I think should be test this PA

schematic

utput stage for 'Amplifier Motherboard' work in class E with tracking dawn converter for rail voltages. Rail voltages for outputs is +/-6V DC, and converter increase rail voltage with input signal up to +/-120V DC, and thats mean over 90% efficiency like in class D, but with class AB sound quality.
Power will be 1800W with only 4 pairs of outputs + mosfets for converter.
I will share schematic soon.
hi apexaudio
greetings hope you share schematic of this amp
thanking you

YAMAHA, CROWN and LAB GRUPEN use similar high efficiency circuits.

apex,
what particular model of crown is this

Xti

Hi Mile could be the tracking down converter can be applied on any amp like b500,step of h900 replace with this tracking down converter?

Yes CROWN do this on xti, same circuits as xls (class AB) or pulse (class H)...

Made for testing, and now this is my favorite home amp. Powerfull, great sound.

HI APEX SIR,
can u share this amp pcb layout in pdf. (top and bottom).

HI APEX SIR,
can u share this amp pcb layout in pdf. (top and bottom).

what is the size of the kelvin amp pcb?

 

[suryadi5417]

Basic from AX14

May i post this my own diy in this threat ? Schematic from the first post i think ...
Mr. Miles can i use TIP31C for bias driver ?
