Okay, here's the situation.
I just got a new Outlaw 7200 amp and I'm experiencing dreaded hum.
Things I've done so far:
- Disconnected cable TV (have a Jensen Isomax anyway)
- Disconnected the pre-out input cables from the amp.
- Disconnected everything from the amp except for the cord.
- Pushed the amp to a different outlet.
It still hums regardless, and quite loudly at times (it varies from none, to moderate, to high hum) and tends to get very warm to the touch.
I have found when I power up my receiver (Harman Kardon 235) with the amp on, the amp's hum either gets a little louder or completely stops as the receiver "boots up" for two or three seconds. When the receiver becomes operational, the hum returns...
Besides the hum, the amp appears to work fine and sounds great.
The hum sounds like it's coming directly from the two big toroidal transformers in the front of the amp.
I ordered a PS Audio UPC200w/Humbuster , but I'm weary whether or not it'll do anything...even though the problem I'm experiencing seems in line with their "Fixing Hum" article.
Anyone have any thoughts on the device or my problem? Any help would be greatly appreciated.
