Hi all!
Unfortunately my receiver has multiple noise problems.
1. Constant hiss at any volume, even volume pot is on 0.
2. Variable buzz only in the right channel, which depends on volume pot position. (when the buzz is present, the left channels hiss also changes a bit in the same way)
I'm sure, these are coming from pre-amp, because when I disconnect the pre-amp and only use power-amp, it's completely silent. These problems are present on all inputs and independent from any controls (bass, treble, high-low filter).
I made a video with a connected pc speaker turned up in volume for better hearing of the problem:

Thanks for any advices!
