[bremen nacht]

I'm having a bunch of these made:

anyone want one/some?

Could be keen for a few. Let me know expected pricing and which variation your building.

Gooki, I was really just looking to do a group buy of bare boards which are, of course, common to all variants. The setup cost is a lot more than the price-per-board; I'm hoping to get at least a dozen.

But it might still be worth sharing an order for the dual mosfets, as the price break is for 10 pieces.

ps: for 10 off bare boards, about 20 US dollars per board (plus shipping, tax, yadda, blah)

I would be interested if more people join the GB (and the price per board drops quite a bit).

 

[jp88]

If enough people were to join to drop the price a bit Id be interested as well, possibly interested in 4 or 5 boards

If I do 20 boards it works out at about 10UKP per board including tax and shipping to me.

How about the FETs then? group buy on them also?

You mean IRFI4019H-117P? I'm interested.

Yes, I'll be building at least one board to the variant that uses these.

Are you interested in the board also?

 

[Markus2006]

I have already 3 boards. I need only the MOSFETs (6 pcs.).

OK, I can do that.

I'll leave it a couple of days to see if anyone else is interested, then I'll email everyone who's shown an interest and work out who wants what.

 

[mr coffee]

I'd like a couple of boards and semis.

Is there any progress with the order?

Confused



Could anyone tell me the difference between the D and the S version?
The pictures on the Datasheets are differences, but the schematics seem to be the same?
Have anyone listened to this amp?

Right, two and a half years ago I said 'I'll leave it a few days...'.

I've now sourced all the bits. Any interest? A complete kit works out about 50GBP, the 2x250W variant.

How about just the boards?

Happy to do just the boards. Price will depend on how many.

D is through-hole, S is surface-mount.

I'll be doing the D version; surface mount seems a little pointless on this board as there are so many through-hole parts and it just means there are parts on both sides of the board, which is no smaller.

Did you know you can buy it for less?

That's cheap.

Truly the West's economy is ****** when China can do for less what we are trying to do for no profit.

Mods, lock this thread. I give up.
