Hello guys.

The first group buy closes tonight. Tomorrow I will start contacting the GB members through PM asking for email addresses in order to send invoices for the confirmation charge.

I will post here again just before I start sending PM and will update GB progress regularly.

Thanks a lot for the interest.

Is there a psu pcb that is recomended for this amp?

Would it be a good idea to wait a little to get to hundred?

Hi.

You can use any basic linear dual power supply with at least 10000uF per rail per channel. I have not tested an SMPS with this amplifier but I guess using them should not cause a problem.

Total number of PCBs printed will be same as the number of PCBs confirmed. Still, if all 90 boards are confirmed then I can get a 100 printed and keep the price per board to $8 and also have some in reserve for anybody joining later. :)

Hi Shaan :),

Please, adjust my number of boards from 4 to 6 as I will give a try with the ECW20(P)N20 with the modifications you did give to us. As you did write it : the stability of the amp with my speakers is not sure, I will have to look at this.

Thank you Shaan for this nice power amp.

Best regards

rephil
 
These pictures show the two test boards I got printed last month. The final boards will look same except two biasing diodes removed and a biasing trimmer and the jumpers added (as shown in the following layout and apparent board looks screenshots).

Shaan, just a quick thought on the layout: If you turn C11 and C12 90deg, then it looks like there might be space for mounting holes on the other edge as well (?).

If so, then the screw holes for the LAT-FETs could be made larger and it would be optional whether to mount them in contact with the PCB or not.
