WTB Firstwatt Clone F2 PCB boards

[belkinmousepad]

I'm in!

Just added myself for 2 sets. I totalled it up to 46. Hope this goes. Let me know if anything else needed at this point
Thanks 🙂

Some news?

 

[AlanElsdon]

Go on - in for a couple - watt else I am going to do with my time?

 

[Peter Daniel]

Will do it, no problem.

IS STILL OPEN ? I'M FOR TWO AMPLIFIER+ POWER SUPPLY SETS
HOW MUCH IS IT?
THANKS

Updates on this? Should I be sending payment?

 

[Peter Daniel]

Of course it's still open; the more the better. I'm still working on a layout.

Peter, how long you will think that will take to make this amp board ready? i was thinking about wait until this will be done, so i pay just one shipping fee

 

[Peter Daniel]

I never charge extra shipping on F boards, shipping is always included in a price. I would also suggest not to wait 😉

Someone have the correct Mouser/Digikey BOM?

Someone have the correct Mouser/Digikey BOM?

I think that will depend on the board layout Peter comes up with.
This amp puts out 2amps or 100W a channel, and the 1 ohm resistors also really belt out heat.

I think a thick film resistors attached to the heatsink replacing these would save space and keep from melting the boards.😀

C4 needs to be large enough to avoid turn on thud, bad for FR speakers... I use 33,000uf

We know what the power supply looks like, it uses 4 X 1 ohms vs 4 X .47 ohms like the F3-F5, and Peter already has those around to view.

Here is the board layout I used, stolen from other thread.

Any updates

Just wondering if there is any news on these boards & BOM?

No real rush - after all there are 4 others to build!

 

[Peter Daniel]

I will have it finalized this week.

 

[SanJoseBong]

I want one (Whatever needed to make a stereo power amp).

I will have it finalized this week.

any news on this layout?

Put me down for a full set of F2 boards Daniel.

I have a question for you Daniel. Are you going to increase the room for capacitor "C2" so that larger film caps can be used to bypass the 15KuF output capacitors? I have some 1uF 200v "Vitamin Q" capacitors that are just begging to be included in this amp.
