Mauro Penasa's MyRefC LM3886 Amp Kit


Group buy status: CLOSED THANKS GUYS

Mauro, Russ White and Brian Donegan are responsible for the design of this board and we thank them for allowing us to use it in this Group Buy. You guys are great.
Udailey and schro20 are arranging the buy.
Uriah is working on the boards and working with board houses to get proper execution of the design. At this point the prototypes have been ordered and one has been successfully populated and tested. It is working and sounds wonderful.
Peter is working on the BOM and kitting. Thanks so much Peter. I know it is a lot of work.

+++WEBSITE+++
I am setting up a website that will contain concise materials about the board/build/BOM so that you will have somewhere to go to if you just want quick info. Give me a few days to get it running.

Background

[Original Announcement and Discussion Thread]
[Group Buy Thread]

This is an innovation in LM3886 amps. It is NOT a chipamp. This board goes far beyond chipamp status. Please read at least the first few pages of the original announcement.
Some things I love about this amp is the new realism to voices as well as the delayed start to remove turn on thump. It is nice to have the speaker protection circuit as well.

The offer

We will offer a real nice looking pcb in green and white as well as ALL parts necessary to populate the board.

Payment

Paypal is the preferred method of payment and the currency is US Dollar.
There will be no COD, Checks, Money Orders. You do not have to have a PayPal account as long as you have a credit card. PayPal will simply bill your card. Convenient :)

Shipping

Standard shipping will be via USPS. All packages must be trackable and have delivery confirmation. I will calculate the shipping price and let you know the total once the boards and parts are weighed.

The ordering and payment procedure

1 Decide how many Kits you'll order. Write it down on the list.
2 [Email me once requested], so I'll get your email address. Please also email me your contact info, address, phone number and forum ID.
3 I'll send you a Paypal bill.
4 You'll pay me.
5 I'll make a note on the list that you have paid.
6 When the letter/package is ready for sending I will ask for the shipping fee.
7 I'll make a note that I have sent you an another Paypal invoice.
8 I'll make a note when I have received the money and when I have sent the goods.
9 I'll send the boards and note it on the list.
10 You'll make a note when you have received the package. (I'll appreciate that)

Sign up here, list how many kits you are interested in. When everybody interested has signed up, I will calculate the total amount of boards that will be ordered. When the price is set, please follow my instructions for payment.

Price per kit at a minimum total of 100

$35 Mono $65 Pair of Mono

Shipping cost will be charged when I know what the cost will be for each member. It's hard to calculate because some of you will order different numbers of kits as well as living in different countries.

All business will be done in USD it's possible that small changes in costs will occur.

Please Please do not request shipping charges before we even know how much it weighs. I will not figure it out for you at this time. You could assume one pound per kit and go to USPS and try to figure it out. That would be kind. Having 100 people ask me to do that for them is not.
