That's normal -- especially on stronger signals.

FAST or SLOW (I think this is a good real world, simple, bottom line

" Swapped out the 51k R1 and replaced it with the 33k.  Powered up and I
seem to be doing much better.  Turnnig the AGC on when there are no
signals present only drops the hiss by a small amount."

So does mine, but I didn't have to change R1.

"The FAST/SLOW test worked for me ... anybody else think this is a useful
test for diagnosing over-powered AGC?"

It's certainly a good test to see if FAST/SLOW AGC is working properly.
