2385 power rating

[furnitureguy]

I will be picking up a 2385 tomorrow morning (I am excited!).
I have heard many instances where vintage Marantz receivers tested higher than the stated power. Anyone have any info on independent testing of the 2385? Did it clock in at more than the stated 185 wpc?

I'm sure it does. I'd be surprised if it came in at less than about 215WPC.

I have a friend that has an original 2385, and I have the scope and dummy loads to find out what it makes. Now to see if I can get Joel to play along with the experiment.

The problem is defining your clipping point. I define it as the point where the amp hits 0.5% THD (so yes, I'm monitoring with a distortion analyser).

You have a point there, sir. I didn't think of that.

What does your waveform (let's say 1KHz) look like at .5% THD? Any visible flattening of the peaks at that point?

 

[EchoWars]

Yes, the peaks are just beginning to flatten (with SS gear). Usually.

I'm game. I'll bring it over if you want.
