[R-390] Limiter on R390A vs R390

Good Morning!

 

I notice a substantial difference in how the limiter performs on my R390 vs
my R390A.  Let me explain, the limiter on the R390 seems to be much easier
to use as the control performs much more finely and is much easier to
control.  The R390 cuts off completely much higher in the adjustment range
than the R390A.  In the R390A, the limiting action is only up to about 3 or
4 on the dial before it cuts off completely.  Further, the R390A, is nearly
impossible to adjust right to the point of cutoff.  After the adjustment is
made, the action takes a second or two to settle out.  Backing off the
adjustment does nothing for slight movement, then audio comes back suddenly.

 

I suspect the R390A has an issue but I wanted to confirm that the operation
should be the same or not before I dig into it.
