This is an ACA Mini PCB with artwork designed by Mark Johnson following the Nelson Pass circuit. It is very close to the artwork released by Nelson Pass for the boards which were given to some lucky participants of the Burning Amp Festival. Mark was gracious enough to produce a number of his boards and give them away: I was one of those recipients. I have built the amp using this "Almost Clone" board and it works and sounds fantastic. It was suggested that a group buy for this "Almost Clone" board get started...so here we are.

This group buy will run with the quantity limited to 50, and the time limited to two weeks, whichever comes first. We will be shipping to addresses within the continental US during this first group buy. Depending of the success of this buy there may be another and the parameters may be broadened to include the rest of the world. For now I'm trying to keep this thing as simple as possible.

Photo's of a completed amp can be viewed in the ACA Mini thread #462

Of course you will be using the Nelson Pass article for a description of the circuit, build guide, and biasing instructions found at the beginning of the ACA Mini thread #1

Cost of the board will be $12 with $5 in shipping to an address within the Continental USA.

To purchase a board simply copy the post with the current list of names, add your name and quantity, update the total, and paste to new post.

This Group Buy will end on January 22, 2022 at 12:00pm EST

Thanks for looking,
Kevin
Kevin,

since I am new to ordering boards, do you know how long does it normally takes before you start shipping?

Thanks

Since I’m new to running group buys I have no idea (insert groan from the crowd ). We do have some advantages: 1) I’m self employed and this is my slow time of the year. 2) I have a supportive family which is willing to help. 3) I’m exited about this group buy and want to get boards out as soon as possible. Sorry, that doesn’t really answer your question, but we’ll do our best.

Usually the slowest part of a Group Buy is collecting the money from diyAudio members, before placing the order (!!). There are always a few stragglers who forget to pay / clog their inbox and can't see messages / get distracted by other important aspects of life / require personalized hand-holding because PayPal is harder than brain surgery / and so forth.

My own guesstimate, which OBVIOUSLY is not a promise, would be: 6 more days of sign-ups, then 8 days for KevinHeem to collect the money, 1 day to place the order, 15 days** in the PCB fab, 4 days for international shipping and customs clearance, 2 days for KevinHeem to print mailing labels and pack shipping envelopes, 1 day for him to stand in line at the Post Office, and 4 days shipping to your CONUS address via First Class Mail.

Note**: As far as the PCB fab is concerned, an order for 32 boards is not considered Rapid Prototyping. To them, KevinHeem's manufacturing "job" is a Small Production run, whose speed thru the fab isn't mega priority super hot lot.

Hi Kevin -

First - thanks for taking on what will surely be a fantastic GB. Really looking forward to hosting another group build, and this seems like the perfect project. The Itty Bitty Amp Camp Mini Amp Camp. I'm thinking it will be fun for family and friends.

In my (one time) limited experience. I wish I had used some sort of online spreadsheet for signup vs. a list managed in the thread. Inevitably, as you've now seen, it can be tough to manage. Randy has one of many exceptional (IMO) examples for his Aleph GB.
