Default "Proper" TDA3116 PCB

Dear Santa,

I know you're super busy, ... but could one of your elves (maybe that anal, dental guy) spin me up a 'proper' 3116 PCB!:

TPA3116D2 Amp

TPA3116D2 Amp

TPA3116D2 Amp

TPA3116D2 Amp

TPA3116D2 Amp

TPA3116D2 Amp

TPA3116D2 Amp

and did some cross listening:
TPA3116D2 Amp

It has to have proper hf SM bypass since it's a 'digital' chip, like the EVAL:

Errr, I think the heatsink is overkill, so a smaller one that lets me get the PS Electros right next to the chip, would be perfect!

... and I'd love big, proper differential input caps, sm and th would be awesome! (even for single ended). You know how I love to tweak, Santa.

...

And of course retaining the ability to choose the switching freq is perfect.

Er, and ... cheap would be good too Santa ... you know, ... thanks Santa!

Cheers,
Jeff

What do you think a cheap board with all of these features should cost?

I'll bang out and sell a PCB, however you'll be putting parts on it yourself.

Icing on the cake might be an actual kit, with the IC soldered. All board components supplied with options/tweaks indicated (not supplied). Nice heavy copper traces to support multiple reworks over time.
IOW, a really good sounding basic all-inclusive amp board kit with a relatively straightforward upgrade path.
Would be interesting to see it costed out. Won't be able to compete with the China connection stuff pricewise, but the abovementioned qualities and features should make it worthwhile.

Have to dig back through that thread. Didn't see that it was available with all needed components included (but not installed) for a price. Got the impression that it was available as a board with (or without) a soldered IC but only a BOM was supplied - not the actual components.

My apologies...
