O2 Headphone Amplifier GB
 
Hi all,

I want to host a GB for this fantastic little project - an objectively designed headphone amplifier.

Details
You can find the discussion thread here.
You can find the designer's blog (RocketScientist aka NwAvGuy) with further juicy details and measurements here.

I will get a proper quote in due course, but I have had an estimate which will be good enough to get the ball rolling and see if there is any interest. These estimates are based on me buying 50 boards but I'm sure we can break that number! As we begin to approach a larger number, I will start getting more refined quotes.

Shall we set a GB end time of 31/08/11? The GB can be extended if it doesn't reach a big enough number by then.

Price
1 PCB inc shipping (US): 5.22 ($8.53)
1 PCB inc shipping (UK): 4.10
1 PCB inc shipping (EU): 4.87 (5.58)

Price Breakdown
The price includes the cost of the board, the cost of packaging materials and the cost of postage. There is a 5% buffer included in the price to cover boards which may get damaged in the post or other unforseen circumstances. If, at God's discretion, there happens to be a few pennies left over, then I will buy myself a pint with them :D

Ordering
When you are ordered, please state HOW MANY you want and the REGION afterwards, so that it is nice and clear for me.

Example: "1 x (US)" or "1 x (UK)"

Current List
If you see any mistakes here (e.g. I have put you down for too few/too many boards) please let me know asap.
