Hi Guys,

The PCB's were submitted this morning, so if your name is on the list, it's there to stay.

I ordered 40PCB's so people are still welcome to add their names to the list so long as the number doesn't exceed 36 boards. When the total is 36, the boards are sold out.

Looks like the majority of people are opting for the SMD parts, which is great. Prices aren't going to drop much more than they already have, but there are still a few parts that could benefit from more people.

I took a full new set of measurements this afternoon that reflect the exact circuit and grounding scheme on the PCB. As expected, things look superb.

Cheers,
Owen

@Owen

Sounds good, thanks to post the measurements.

 

[RichLund]

Hi Owen

Did you get a price on the boards yet?

 

[jameshillj]

I just add my name to the bottom of the pcb and parts lists, yes? Thank you.

Do you think this could successfully drive an Aleph J? (with digital volume control instead of a pot)


Thanks

Dave

 

[opc]

Hi Dave,

This would be a perfect match with the Aleph J providing you use the balanced inputs. The input impedance of the Aleph J is no problem, and it has just enough gain to be driven to full power by this circuit.

Definitely an excellent match!

Cheers,
Owen

Hi Guys,

Great to see all the interest in the boards and especially the SMD kits. It looks like everyone who wants a board is also looking for an SMD kit, so I'm going to simplify everything and just order 40 sets of the SMD parts. That means the boards now come with the SMD parts, and there will be a single price for both.

Speaking of pricing, I've got everything more or less firmed up. The PCB's might end up being a tiny bit more if I have to pay taxes or brokerage on the order, but so far it's looking like:

PCB: $19
SMD Kit: $23
Shipping: likely about $3 to US and Canada, not sure yet for overseas.

When the boards get here, I'll be building one up and testing it, then I'll start the painful process of doing the kit-up for each board.

So all told, it'll certainly be under $50 including shipping, which is pretty good for a board with parts! There's definitely power in numbers.

Cheers,
Owen

 

[Yunick]

Great news Owen! I'm really looking forward to this build

When do we pay?

 

[compressit]

Many many thanks

When the boards get here, I'll be building one up and testing it, then I'll start the painful process of doing the kit-up for each board.

Please remember there are many of us that are profoundly grateful for the contributions made by the more knowledgeable members of DIYA.
My system would still be the pathetic POS it was before I found this place and it's people a few years ago. The stuff I build from knowledge gained here is way above average.
