We are using SSM2019 Self-Contained Audio Preamplifier.

We have observed the noise on our system. Pls refer to the attached file.

It is irregularly-recurring noise and the repetition is not regular.

We would like to know the cause of this noise.

It would be greatly appreciated if advice could be gotten.

Sincerely yours,
