You know, I might need to retract this......
The amp was sitting with the top panel open this morning, I powered it up and there was no buzz. This wasn't that unusual, because it doesn't buzz every single time. But thinking back to studeb's issue I put the lid back on, powered it up, and it did buzz. Lid off, amp on, no buzz. Lid on, amp on, buzz. Very reproducible, until the amp warmed up enough such that the buzz with lid on stopped.
It has definitely buzzed in the past with the lid off - the recording I made yesterday was lid off - so there is more to it that just that. But it is certainly an interesting phenomenon. I will ground the heatsinks tonight.
