Out of curiosity, what make/model speakers are you using? If a driver wire connection is compromised, it could create the very sound you are experiencing and it could be intermittent.
They are KEF 201/2. The KEF Reference 1’s of their day. The intermittent nature of the noise is frustrating. I’ve verified cable integrity

Out of curiosity, swap the left and right speakers only, and see if the static noise remains on the right. That will help rule out your speakers.
Good idea I’ll do it when the static returns. Today is the first day of nominal noise in a few weeks. The intermittent nature is frustrating.
If the noise stays on the right with the speaker swap, the best way to isolate the BHK300 amp as the cause is to then swap the amps only, not anything else (IC’s, speaker cables, or power cables…just the amps!). I know it is a pain, but that would be a definitive troubleshooting step that would 100% isolate the right BHK300 mono as the cause.
People, please stick to the topic of this particularly issue; the sound of static randomly coming from the right channel speaker.

Not using BHKs. I had this sort of ‘static noise’ problem once, coincidentally on the right hand speaker, and it turned out to be a poor speaker cable connection. But you said you had checked all your cables.
I pulled and reseated all of the cables. I’m doing double runs, so I swapped around positions on the amp too.
A post was split to a new topic: BHK Amplifier Issue
As of now, James has done what he can to sort this out and PS Audio is getting involved in addressing the amplifier problem. Thanks to all for their advice and insight.
