Got'cha!

Thank you.

I will discuss payment options in a bit

Typical lettermail postage to off the N.A. continent is ~ $12USD. However I would strongly recommend making it $14USD for Small Packet Airmail, as we've had a 50% lost-mail rate, especially to south pacific countries with oversize lettermail or ground parcel

A question to:

mbcouple - 1 or 2
matjans - 1 or 2
AndyB - 1 or 2
doobooloo - 1 or 2

Who wants "1" and who wants "2"? I ask this because I want to close off the first round of boards at 25, as the PCB maker wants to make them in lots of 25. So if a couple of you take 2, we can close off the first round and begin the next, with possible carryover.

Payments. I'll coordinate this too, as I have a good relationship with the PCB dude.

*passes around collection plate*

Cost of one board is $27.50 USD.

Shipping for one or two boards is to be added:

Canada (lettermail): $2.20 USD
US and US dependencies (lettermail): $3.40 USD
Rest of the world (small packet air): $14.00 USD


I accept:

- PayPal (preferred). The address is geek <at> classicvalve <dot> ca
- hyperWALLET. The address is geek <at> scorpiorising <dot> ca
- International money orders (Western Union preferred of the M.O.'s).
- Pink US Postal money orders.
- Certified cheques (Canada/US only).

Please make the paper stuff payable to and send to:

Address removed at Geek's request.

It will take around 6 to 8 weeks for you to get the boards from the time enough money is collected and the process starts, depending on how cantankerous postal and customs are.

** edit **

We need updated gerbers first though with the corrections

Well, here are the mods that have to be done...

(1) cut corner off the LM1085-3.3 (foreground) and shave transformer (background)


(2) Dremel clearance into the case for pins on the PCB:



(3) Cut a quarter inch off the volume pot shaft.


I can turn the LM1085 90 degrees which fixes (1), I'm working on (2) now. Guess you'll have to live with (3)

update:

Even if I replace the 3.2VA +3.3V/5V transformer with the 1.6VA transformer, I can't clear the case 100%. I could replace both transformers with 1.6VA units and have perfect clearance, but I fear the +-12V transformer will overheat.

You'll still need to dremel and tape as shown above, or use the 53mm high Hammond 1455N1601 case instead of the 30mm 1455L1601 case - doing this fixes all clearance problems.

I will take 2 to further the cause.
Thanks
Hans

[AndyB]

I take 1 PCB if we still reach 25

new problem!

The DAC uses the Qualtek 770W-00/02 power inlet. Problem is, Digi-Key only sells these in a quantity of 100 and I can't find any places which sell in a lower quantity than that.

But it's $51.60 USD for 100, which isn't so bad. Geek, can I suggest you place an order for these and add them to the group buy?

[samgotit]

I'd like one please.
