Thanks, Paul. I have and there was. Unfortunately, there isn't much real
information, no data one can use, just vague descriptions. Next time I have
the clock running I'll make a video, put it on YouTube, post a link here.
Perhaps someone else has one and can compare. What would be nice would be
to find someone who had a 113AR when it was new and could comment on the
noise level out of the box.
