I think you missed where I said that my recent 7125 does have a seal. The photo, however, shows no seal. Therefore the photos may not be accurate.

It is not UL who would pay for a house fire. It would be you insurance company, and I don't know if they have it written into their policies that electronic devices must have a safety rating, but I wouldn't be surprised.

Which Outlaw amps do you have that don't have any rating? I mean you did check the back of the amp and didn't just count on the photo to be accurate, right?
