Default Someone's DIY Aleph J for Sale

Checkout this guy's DIY Aleph J for sale. My favorite feature is the bare wired thermistor. I hope someone knows what they are doing, and the hot leg doesn't touch the case.

There have been a number of Rawson efforts appearing on the net.

Needless to say, these are not authorized.

Default Meaning he's trying to commercialize your design?

Assuming that's so, can someone tell me how to post some kind of negative comment to that effect on Audiogon? Someone thinking of buying a ripped-off design out to know what they are doing, and that the designer has graciously shared his knowledge with DIYers on the condition that it not be used for profit. If I knew that about a piece of gear someone was trying to sell me, I wouldn't touch it, and I'd do what I could to make it hard for him to sell it to anyone.

Hmmm, maybe there's something potentially karmic about that naked line current wire lurking so near the metal case? No. too evil of a thought.

Personally, I can't believe that he actually wants $425 for it. It's a decent quality execution (excepting the thermistor), but it's nowhere near professional. And I doubt there's that much into it in parts and labor.

Peace,

Dave

The ventilation slot in the back is as charming as a 3-button rear flap in a Long Johns of the Wild Wild West.

Are they selling off 1 they made for themselves or started a small business?

$100 for alum
$100 for heat sinks
$50 for the transfo
$150 boards, parts, connectors, wire.

It's close, I think. What if they bought everything new? Who knows. Point is they'll probably get low-balled on Audiogon anyway.

Most people on Audiogon know Pass Labs. Just email the guy as a concerned member and warn them that what they are doing may not be considered very cool by the community. Maybe they guy got stuck and are selling off a DIY project to keep their water on. Things aren't that great right now out there. If it were me, I would sell it for less than what I paid for parts. But that's me and I've never sold one of my Pass DIY projects. I'm going to pass them down someday...no pun intended.

If they're building and selling multiple amps...well just another jerk messing up the works.

Just playing devil's advocate.

Vince

I couldn't resist.

Sent email to seller:

"Some people think you might be profiting off of Pass Labs DIY projects meant only for personal use. This includes the designer himself. If you are, I'd say STOP.
You could face legal action by the designer. It is a patent design, not to mention you'd be screwing it up for the rest of us who respect Nelson Pass. Think about what you are doing if you are infringing. If you're not, go in peace.

I believe there was an Aleph 30 using the Peter Daniel boards, and a F2 & F3 sold under the Rawson name recently. Hopefully he's just clearing out his DIY collection. Unless a person is seriously scrounging for parts, it's tough to make money at $500 or less on a one off DIY amp - as Vince pointed out.
