Wow, those look much nicer than the epay junk I’m using now!

Nice boards, xrk971.
Where do you order the PCBs?

Thanks,

I have been using JLCPCB recently.

Looking very nice indeed! Please tell us how it sounds when you have it up and running!

Are you looking for the schematic for the HM3S board?

Thank you

 

[Sensation45]

you could just google it

which one is this schema ?

@ Sensation45 here is the Goldmund 29 diagram you are looking for

Thank you

Looks like a Mimesis 9 to my eyes.

Sensation 45, Is it possible to get a copy of the front end pcb schematic? For years working on building a pair of Telos 2500. Thanks

Are you planning on using the 2sk1058/2sj168 pair?
IMHO that is not a good idea.
The 2sj168 is really not very good.
Use Alfet 08N16/08P16 or BUZ900 types or the more common EXICON EXC10N20/10P20.
They are all much close clones to the original Hitachi pair 2SK135/2SJ50

Agree, I mentioned my AB test in this thread before, that 2SK1058 is not comparable to Exicons.

Try to use BUZ900, or Hitachi 2SK134/135, though EOL. But you can still get new and good Exicons from Profusion in UK.

Huge difference will be noticed. The 2SK1058 has weak and tough bass, the highs is not as clear as Exicons.

When listening to 2SK135/Exicon, the bass is punchy and vivid, the high is warm and charming, soft.

I built a Goldmunduino, a test platform of Golmunds.
There are interchangeable input module, capacitor test slot.
The Nichicon MUSES BP and Elna Cerafine, Silmic II are good as feedback capacitor.

Has Goldmund used the exicon parts in their products that anyone has known?

Yes. Modern Goldmund models use Exicons parts, even their headphone amplifier, Goldmund uses Excion's Lateral MOSFET as the HPA's power stage transistor without heatsinking.

2n5565

Please help me with an opinion, what do you think about these 2N5565?
I bought these disassembled parts from TAOBAO (10 pcs)
They were measured according to this scheme.
This is what the measurements on Tracer Curve look like.
Do I have a chance to be good?
Thank you very much for any help:noroc:

 

[domenico80]

can you find the new dual fet 5566/64?
I replaced them with IFN 411

 

[domenico80]

Yes. Modern Goldmund models use Exicons parts, even their headphone amplifier, Goldmund uses Excion's Lateral MOSFET as the HPA's power stage transistor without heatsinking.

where can i see the data sheet of these power amp mosfets? I can not find them.
I wanted to compare them to the IRF 240 and 9240
