I just got word that the PCBs have just shipped, should be here in maybe 3-4 days.

Just in time for Xmas.

That was quick X, I assume you will then get these in the mail after Xmas now, once the mail peak season rush dies down.

 

[Vunce]

Great news X!!
Looking forward to stuffing those fat blue pcb’s 😀

 

[xrk971]

DHL shipments from Shenzhen usually take 3-4 days to get here. So before Xmas I expect. But shipments via first class post to Australia will take another 7-14 days usually.

Just got note from DHL that boards will arrive by end of day Dec 18

Thanks, Jwjarch! It’s a keeper of an amp for sure. I think my 4Ux300 Dissipante has been officially removed from “development” chassis to be permanent home of the Nirvana.

As promised, the PCBs arrrived today. They are thick and look real nice with the gold and all. I wish I had these for my amp, but I am not going to build another one just to have a blue board! However, some of us will (Vunce). 🙂

These snubbers remind me of the bling that JPS64's via stitching used to have before we went with tented vias - you could hold up an amp board and see through it:

Very nice work JPS64! Thank you!!!

 

[Vunce]

Nice work X & JPS64!
Your right X, my OCD will keep picking away at me until the cool blue pcb’s replace the green ones with the desoldering scars, haha!! 😀

X, PCBs look cool and of high quality.

Now look forward to people building and listening!

Believe it or not, these cost almost as much as the main PCB.

Why is that? Is it because of the shape or dimensions?

 

[xrk971]

All boards under 10cm x 10cm are priced similarly.

 

[avtech]

That's good to know that custom shaped boards cost the same. Cheers

 

[jwjarch]

Beautiful work guys! I never get tired of staring at all those little vias. Have you ever thought of making a board without them and measuring the performance of one with and one without? Would be quite the experiment I think.

 

[gary s]

Again JPS has done brilliant work for you on these pcb's.

Are you looking at getting these in the mail before Xmas?

 

[xrk971]

I will send out in 2-3 days, so yes, before Xmas.

 

[gary s]

Thanks for the update X, these will be a handy New Year's present for 2020.

Just to confirm, 2 main AN pcb's and 4 off Fet helper pcb's to make up stereo pair.

 

[xrk971]

Yes
