VKB Mamba Vintage potentiometer spiking. How to fix?

Postby hazel » Sun Sep 27, 2020 17:10

VKB Mamba Vintage
The THR and PROP potentiometers becomes noisy and generate spikes. How to care for potentiometer? Clean? How to clean (with what)?
Which model of potentiometer (name etc.) is used in the kit if I have to replace one?

Is there maybe a parameter of filter in VKBDevCfg for noise reduction from pots etc?

You can use it in the 10k-100k range. In order not to suffer with the removal of the old resistor, I suggest just having a bite to the conclusions and singing to them, as in the photo.

"Singing"? Sorry but I don't understand, maybe something lost in the translation...

It was meant to solder, although this action in Russian can be described in slightly different words. So it happened. The main thing is that you understand.
Nobody forbids singing about this :) .

He he. Ok. Thanks.
Is there maybe a parameter of filter in VKBDevCfg for noise reduction from pots etc? Some kind of smooth etc.

The HF Filter could propably counter this. Try a Value of 2, or even 3.

But if you want to clean the Potentiometers: CRC Tuner 600.

Try this first, Filter 6-7, Thr = 0, HF 3-4.
