DIY Gene on eBay - Aleph 5 boards

[monarodan]

Hello Everyone!

Sorry if this is a double post - I got an unusual message and I'm not sure if the first post succeeded (I can find it, so I'll assume it got lost in the ether).

I have been planning to build an Aleph 5 for way too long now. In my travels I came across a seller on eBay called "benytlau" who has an eBay store called "DIY Gene". He is selling an amplifier based on the Aleph 5 (you can bet it's identical) called the M-10.

Here is an example listing of a pre-assembled and tested amplifier module:

The seller is based in China, while I'm based in Australia (added risk to me). The seller does have very good feedback and replied to my inital queries very quickly (and in very good English). Has anyone had experience with this seller? Any thoughts on the products? Any questions I should make sure I get answered? What about the price? All comments welcomed!

Thanks in advance,

Daniel Paull

Opinion?

There is no fun in building a stolen design.

find another way to build it;
ask for help and advices here ,and you'll have both.
steal whatever you want (as we all other do ) for personal purposes (meaning -I want one amp ) ,but do not support someone's illegal business.

no offense intended to you.....

Wow, that's pretty bold, and as far as I know it's against Ebay policy. I'd bet NP could shut that down with 1 email.

saying Circuit design based on Pass Labs Aleph 5.
and not pass labs aleph 5, kinda covers his butt legally.

he could just turn around and call it a m-10 class a amp. under another ebay account its hard to stop these guys.

im not going to say how you can have up to 5 accounts on ebay
with the same adress but i do

and no i dont use them for illegal purposes

cheers

Yeah, I'm not full bottle on the copyright issues and patent infringements that this person may be facing. So, it's a heads up the NP I guess.

For all I know, this fellow could be authorised to sell the amplifiers. But, until I hear othherwise, I assume he's dodgy and steer clear.

Really, I'm just after PCBs as this is the one part that I'm going to find diffficult to manufacture myself, and hard to justify the efforts for only 2 amps!

My preferred option is the boards from Brian:

However, his order page states that they are "out of stock". Perhaps I'll shoot Brian an email shortly and see if he can help. Can anyone offer advice on souring PCBs?

The PCB looks familiar. I believe that this individual displayed the layout on this forum a while back and asked for comments and advice. It was represented as a personal DIY effort. This is a pretty distastful situation IMO.

Speaking for myself, I avoid all of these commercial or psuedo-commercial efforts to make money off Mr. P's IP. Do it yourself - from scratch.

Cheers,

Alephs are really not that complicated.
Building them on a vero board has given me the most pleasure. Mount the gate resistors directly to the mosfets, build your power supply and solder the remaining parts point to point. Connect everything with some neat wiring and you’re done.
Don’t forget the blue LED.

I agree with Netlist.

You'll get at least twice as much satisfaction out of wiring the whole thing yourself as you will from stuffing a board that somebody provides for you. You'll learn more about how it works, too. With a little time spent on layout, it will look pretty cool too.

He has other amps for sale too, including a "Jeff Rowland Clone"

I hope Nelson can go after him...
