Knowing and having experienced losses in the hands of Indian Customs, I opted to stay out of the group buy for ra7's awesome preamp boards and decided to etch my own boards.
Okay, here's what I'm getting for USPS flat rate padded envelope:
US should be good to go but let me see if I can do better on Canada, Europe, and Asia. Will checkout Paypal.
| US | Canada | Europe | Asia | |
| Shipping | 10.6 | 29.6 | 39.7 | 40.85 |

Yes, First Class Package International Service seems to be much cheaper. Here's new rates:
These rates are much more reasonable. With those shipping rates, including PCB cost and Paypal fee and $5 additional, it comes to:
Okay, here's the plan:
1. Look at the table above and look at the spreadsheet here where you put your name down.
2. Depending on where you live (US, Canada, Europe, or Asia) and the number of PCBs you want, know the amount you need to send.
3. Add $3.00 for a pair of the gain FETs (STP30N10F7), if you want them.
4. Use the Paypal address I send via PM and send the money. No rush to send the money. I will have PCBs in my hands in a week or two.
If you are not on the list as of right now, send me a PM.
Note that I will use the address in PayPal for shipping.
Let me know if you have questions. All members on the list should've received a PM with the Paypal address.

Hi Rahul
Are we allowed to buy more than what we had written on the spreadsheet...do you have extra? If I could I would buy 2 instead of 1.
Thanks

Yeah, I'm curious about that as well.
Either way, thank you so much for making this available Rahul.

Okay, you two are in but not anymore for now. I need to check but looks like all the PCBs are spoken for.
Important: include your diyaudio handle in the Paypal note. I know some of you but don’t know everybody’s name. I should’ve said that earlier.
Spreadsheet has been updated with two columns: confirmed PCB and FET pairs payment. Thanks to all that have sent money as well as for the messages of support! I really appreciate the good will of the members in this forum.
All 50 PCBs have been spoken for. Hooray!

Another question - what are others going to use for C102 - seems to be an odd value.
Only snap in I see at mouser that comes close is 56uF 400 volts and it is probably too large.
One could always make an axial one work.

RV103 might be okay. But the other two, you want finer control.
Yeah, 56uF, 400V will work. Just make sure the footprint is okay. I guess I need to post that. Let me get that over the weekend.
I cannot emphasize this enough: C102byp is a must have. Even a Dayton crossover cap will work fine there, but do not leave it open, especially with an electrolytic in the C102 position.
Thanks for the advice.
Any reason NOT to use an axial - other than its butt sticking up in the air?
What minimum value for the the bypass cap? Maximum value?
The electrolytic cap I am looking at is a CDE computer grade cap with 4 ohms ESR. Is this typical for this size of cap or is that high?

I wouldn't use a 400v cap in this location, snap in leads will not fit here and will be physically too large. I did a quick Mouser search for in-stock radial lead 47-56uF, 50-100v with 10mm diameter capacitors. A good selection is available. If using a 47uF electrolytic make up the difference with a DC link PP film capacitor in the bypass location 😉
