Very good. Dear Mr. Kevin Gilmore. This will prove. Our design is completely different.

It only needs a rough comparison transistor and power supply to prove not the same design.👍👍👍

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

NOOO i don't publish my schematic 

Just like you can't ask Stax to put D10's schematic. Put it to the open source forum☝️

You do not need the PCB was enough.

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.

 

In fact, there is no need to prove this. Stupid and bored things. Anyone is likely to design him own things. How can you prove this not my design?🤔

so here is what is going to happen.

birgir will use his contacts to purchase one of these if it exists. Then he will determine if he likes it or not and will publish pictures etc. He has yet to publish pictures on the other 2 (or is it 3) stax portables.

If he likes it, and if its really $400 then i will buy one. Because there is no way i can build one for $400.

 

I'm way behind on posting pics off all the shit I've been buying recently but yeah... if it is available I can get my hands on it.  Those portable amps out of China are utter crap though... 

Man. A country that allows so much cheating and deception is nothing but crap.

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

I don't think you can delete all of your posts like that, back in the day we couldn't even edit them. 

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.

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

i will let kung explain if he wants to, but it is highly likely that this chinese product does not yet exist. evidently hvrv is also pretending to sell T2 and KGBH.

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

  • Author

i think the last remaining problem is that the batteries don't discharge evenly. but its highly likely that many other products out there have the same problem. kerry will get to it when he can. chassis etc is all done.

i still think that we can make a more efficient power supply but that requires someone with extensive flyback transformer knowledge and someone that can make prototype transformers. want +/-300 with 2.5 watts of power. plus the bias.

i received a miniature hv supply for the bias from Tajikistan and with modifications it works fine.

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

  • 3 weeks later...

Any news about portable Stax amplifier ?

I am willing to buy it, preferably in a kit - nothing will play less than what you do yourself :)

there is no way this is going to be a diy product.

I understand, and when will it be ready to buy?

I have one more, maybe a stupid question - how are these four amplifiers connected - there is no phase inverter there and looking at the pcb I can see that the inputs in the channels are connected (?) - I'm tired of this matter and I can't sleep because of it - can you explain it to me ?
