This project very slower 😀
I want the see an Clone exactly. Please waiting an other member of Diyaudio make future. I was send orignal schematic and exactly (i'm sure) to him 😀

Well actually I don´t care if they are fakes, as long as they are performing so good as they are. Measures very well in the amp and sounds terrific! They were not bought from China. I really do not know if they were produced there though..Recently, I found that there are 2N556X on Mouser, manufactured by InterFet, named IFN556X. You can buy some.
No offence but your metal case JFET looks very fake. Probably counterfeit from China and Hong-Kong, and, the notorious TAOBAO (Aliexpress).
Just don't trust EOL (End of Life) things from China, though I know sometimes maybe they works.
I know the "China counterfeit industry" very well. They can make anything you want. I ever pretend to be a powerful buyer, and I asked them to produced faked MUSES02 OPamps.
They replied that the cost is about 0.5USD/pcs. If you can pay 1USD/pcs, they could guarantee the electrical performance of the faked OP, at least it would work and makes sounds.
Few days later, they sent me samples of the faked MUSES02 OP. You just can't tell the difference. As a buyer, you can specify the totem, date codes on the surface of OPamps, anything and whatever you want!
Thanks ,
But i've a different scheme and it should be from a Telos 390 Clone .
Build by Pinnocchio from Canada and fully working see
Goldmund Telos 390 Clone
Scheme from Pinnocchio with some tweaked values

Wow, really?!
I've never seen GM with BJT input stage that the schematic you posted.
Is it really a GM clone?
My question too , I also did find a strange scheme after.looking at it .
Maybe someone else may know thé answer . The one I used is the left one .
I think the right version is from Fab .

No, the right one it is not mine.
My GM Telos clone (clown) tweaked version is more about mainly different stages bias current and use of 2 pairs of double die laterals instead of 4 single pairs. I have also use 2sk170BL for input pair.

Hello friends!
I have make and clone GM many times, and failed many times. about 15 times unsuccessful. I have made PCBs up to 15 times, and success when I go about 200 km to open, view and copy 100% Golmun TL400.
After Tl400 succeeded, I continued to do Tl600 and 2500. I'm heading towards TL 5000.
And here are some pictures. I have used 5 years, This is a reference amplifier for my audio system!

What amplifier models are those you mention above? Different Goldmund types? They are kits you bought? Where are the schematics?
The shematic of Telos 400 from Quangho can be seen in post #262.
That is a very good and stable amplifier.
I really do not know what you are saying? The values works perfectly well in the amplifier described.
Why he going through very many time/version for successes?
But I only need 1 time?
I'm send the orignal schematic to some people at this forum. Them having smile as me.
With the parts value of QuangHao. So, Amp can working without fire/damage. But parts value that not orignal, not exactly.
That value are mixer between TL600 and TL5000.

You really need a friend with a bit better English ability to translate your sentence. It is really hard for us understanding your words, and this would cause waste of time and space.
Yes, I'm sorry to all. My English are bad. It's word by word.
I only want the saying: Resistor value on #262 not exactly and other member too.
I will go to over this thread.

I have done: TL 400, and 600, TL 2500, all near the sample schematics!
Image i make TL 2500, you see
Last time i make many PCB, but in Diy i can not public it!
Thanks you advice, and can PM to me! or e-mail!

I had to do 15 times to succeed, just like GM on the sound.
You only made one successful, really that you are too good and great, I would like to study!
Quanghao Happy learning from you!
Best regards
Hi koldby!
Value is not the first important issue,
Most importantly is PCB, is it running stable and great after time ??
The values you have, it's the moment I made them when not directly opening the TL 400, but it still works well. Gm has minor changes in the versions, and the schematic with the product is adjusted to match!
