2 Teufel CB 200 CS Control Station noise
Some time ago I became the owner of a Teufel Concept B200 kit with a CB 200 CS Control Station amplifier. I know it's a very old set, but I've been looking for it for a long time and finally got it. There is one problem - namely, regardless of the position of the volume potentiometer, there is a noise coming out of the speakers, quite loud, with a uniform tone, and just changing the position of the potentiometer does not change it. The noise comes out both when the set is connected to a sound source and when it is not.

Ist dies eine gute Frage?

@tom46654 Have you checked the ripple coming out of the power supply section?

Hi Andrew,
I haven't checked anything yet. Can you describe it to me? I am unfortunately not a super electrician :)

@tom46654 Can you upload a picture of the circuit board of the amplifier? Bilder zu einer vorhandenen Frage hinzufügen

What type of noise, a hum or a crackle?
If a hum, check the filter capacitors in the amp's power supply.
If a crackle, it could be the potentiometer or a loose connection or dry joint to it

Hello Jayeff,
Definitely uniform hum regardless of the position of the volume knob. How do I check this? :)
