Test fit on heatsink:

I will use heatshrink or Teflon tubing on 2nd Panasonic .47r resister as it seems to be little close to wire connector.This board is a single sided,so Mosfets needs to be soldered first before mounting.

Regards,
Sachin

Many thanks to all,
Finished except power switch.
Sounding very impressive, unbelievable ( really i never expect this much quality from this small amp), very nice punchy and clean and perfect bass. By default bias voltage is 9.6v for each channel and increased to 10v. I am using Dell 19.5v /3.6A(60W) DC laptop charger. I have paired with my AR 2ax speakers, AMP driving perfectly those speakers. But i want to test with high efficiency (>90db)speakers. When i connected my mobile source i feel low gain, Connected through B1 buffer with SSP, gain also good along with SSP.
Many thanks to Nelson, Rudy and Sachin to get finished this perfect Cute AMP.
I am planning to go each amp as mono-blocks by bridging mode. I ran this amp more than 3 hrs using my home UPS with out any issues. I am posting some more pics.

Nice work mate.
Once you are completely happy with the operation of the amp I would consider soldering every non-soldered connection.
Connections are evil.

So....what do you do with a couple of amp camp boards that aren't in a chassis...hmmm...how about powered speakers?

This is just a "mock-up". Amp camp board mounts under the heatsink. Change out the speaker inputs for RCA's and drill a small hole to mount the power connector into.

Hmmm.....

I'm thinking of using an angel-eye switch for the power since it has a built-in LED. If I do that, what do I do to on the PCB where the LED would go? Do I:

1) Leave it open.
2) Use a jumper in lieu of the LED.
3) Use a resistor (if so, what value?).
4) Use an LED but not worry about actually connecting it to the front panel.

According to the build guide...

"...the LED is not required for the circuit and you may leave it out if you choose."
