V672X (Telefunken V672a in GDIY51X format)

[[silent:arts]]

That's the way you do it. Or, maybe easier to understand:
set the trimmers to have the same output level at 40Hz / 1kHz / 15kHz

anybody has any file that used it on vocals? how does this clone compares to originals?

silent art, do v672 sound more like v376 or different?

Hello guys,

I finished a few days ago my firtst "Silent Arts" building . Very easy to assembly this pre is the first one in my 51x setup and I am not disapointed at all. Full bodied and rich sound .
Thank you Volker for your stunning work.
I experience a little issue with thte High pass FIlter. I checked and Re checked the board, made some measurements on it and I can't find what is wrong .
Th pre works fine and properly with any microphone test whatever Z Input /Output gain I choose , but as son as I engage the highpass Filter, There is some noise and as you can see a modulated carrier at extremly high frequency (+200kHz) . This happens with low Z input and low output gain ...
I tryed different levels of inputs ... my Generator can only provide 50R Out . Value of V in doesn't affect the scenario .

I did setup the unit by following Volkers and technical instructions, It worked for R26 and R37 but changing trimpot on R 29 doesn't change anything ...
Any Idea ?
Yellow signal is input, Purple is Output; AS you can see the input signal measure is also affected by this trouble ...
Thank you for your suggestions
