Anyone have/ordered the Job 225?

Thanks. More of a tube rush sound as the hum through the woofers is slight. The tube rush sort of hiss is strange? Hiss is a ground issue? I know a 60hz hum is grounding, but hiss? 

I know the unit is two years old. Perhaps the seller will pay for it. 

This is amp sounds amazing on my Harbeth 40.1 speakers! Wow. 

Devil boy, my heat sinks get so hot I cannot keep my hand on them for even a second when I crank the volume. Do you find this to be true? burning hot. 

Jesus! Sorry to say, but sounds like you have something going on there. 
I never felt the heatsinks, but I'll do it tomorrow morning.

Well, you DID also say it was a hum, so that's why I suggested grounding issue. 
I could be wrong. I'm nowhere near an expert on this.

Understand. The heatsinks are only warm at low volumes, but very, very hot at high volumes. At idle, just warm.
