With the scarcity of the crucial parts in this amp, I'm confident that Papa is sleeping well.

Regarding enclosures, you can't stop the counterfeiters. But they will be stuffing them with opamp stuff and class D.

That being said, back to the altered J2 circuit.

I bought some from aliexpress. The vendor was a nice guy who didn't know what they were and he gave me a refund. the only time I bought semis from a non reputable vendor. I have heard that the Chinese govt is clamping down on counterfeiting, which is good news for everyone.

Perhaps you weren't reading, Soundhappy, but they're even allowing Nelson to donate the Lovoltech JFETs for the project. Shocking, isn't it?

Where's the button to delete the fake news and conspiracy theories?

Give me detail and insights on the J2, please. I think it's great how Nelson laid out some bread crumbs and there's been an incredibly creative effort over the space of 10 years to work up some hardware to emulate the Master. That's what's got my focus.

Enjoy.

I'm reading the thread and Mr. Pass didn't submit a veto on building those versions of J2. I see no reason for anyone else to do this. I remember this is diyaudio forum but it's Pass Labs section. The best place to talking about Mr. Pass's amplifiers.

A new trend on the forum ? With the Moderators blessing ?
Counterfeit is when you build something to be indistinguishable from the original, and try to sell it as a real one.

If you build something in your basement for your personal enjoyment, even if you push as far as building it in a case that look like the original, i dont see counterfeit, i see DIY

I second that. Some chilling is needed around this topic.
