I think I heard about the need of that or similar transformer before. I got my 4th boost against COVID, I can wait😀

So the project continues than? As I remember the powering was the main problem always or not?

Is he a moderator here? I would be very surprised.

I thought so myself before. It seems 1984ish delete a person good or bad from the history. Probably it happened before, my inattention. Got a message "不错的耳机" that I have not find on the forum.

@HVRV's messages disappeared. Not that are missing but the remnants are strange. Who could do this himself or the moderators?

To the others: Why this is personal to me, this is not my case. Kevin maybe on Headwise spoke about the mini amp first but more than ten years ago I am sure. I am waiting for it from then. The project restarted a few times. When the head-case server died I told somebody here it was because of ministat amp restarted, Ill fate it could not be accomplished. The truth is I do not need it not travelling much hardly can walk. I am accustomed for the waiting and there is no really good portable amp, I am curious. And now this situation. Yes, I do not like thiefs, everything is stolen some want to eat some want a new Tesla.

You do not need the PCB was enough.

Transistors, the circuit diagram of the amp that counts would you compare them?

So China is the country, what a surprise...

In any country who thinks opamp is a digital circuit can not steal anybody's design. You could be the merchant. If so, I am going to buy an amp from you too.

A few pieces a few times from eBay I do not remember fakes but I am not sure I checked them all. Usually when I could not get from mouser what I wanted.

I have a few from both with the same color as yours they came from Dalbani I think.

TO-252 = D-PAK

I did not follow the thread so maybe not appropriate I have seen 2sa1486s at bdent in stock now. Not cheap. About Dalbani I have some 2sa1968s from them definitely no fake but I bought these ten years ago about.

We are getting older and clumsier. You are much more experienced than me so on my level I think the eye is the main problem the hand can do it only slower. You have to think every step twice and this is the hard part. When you ruin something that feels a catastrophe you should leave it for a time then start again with clear head. I am sorry I have made similar mistakes most long time diy-er do.
