Your box and PCB looks very good

Hello IngemarR,

All measurements results are already been posted few pages ago.
My last pictures is only the same design with better quality circuit-board.
When i will find the time, i will take full measurements with the new oscillator.
You must know that the THD level is much better than all know oscillators...

(EUVL, i don't forget you. I open soon a new wiki for a 2nd group buy of oscillator pcb, but at this time i have only 3 boards asked).

Hello Frex,

some impressive measurements on the "old" board!

Will be interesting to compare the old PCB with the new PCB measurement wise.



Regards,

Frex,

I was curious if the new PCb would make THD better (or worse). Thanks for checking!

The measurement(s) surely is(are) worth showing off again!
Especially the one with the noth filter.


Regards,

Hi,

My question is if i can bay the board?

At the moment i work at a own board, with the 5351, single end. When that fails i am interested.

Can you give me a indication of the price of the PCB of is it "beschtukt"

i am a recording technicion and dedicated to make more simple mic- preamps- combined with ADC.

Greeting

Joost Kist
