John, there does appear to be a peak in L34 near the bottom of the can, but
this is not the proper peak; it is one with higher noise to signal than the
one near the top. The one near the top often does not appear actually to
peak if you are trying to do it by ear. It is better to use an AC volt
meter (analog preferably, and on its most sensitive scale) on the audio
output, and tune L34 to peak the reading. If you don't find a peak, then
you can either try adding a bit to C182, or you can consider just tuning
L34 to give as high output as possible; it's not likely you will be any
noticable distance from the peak anyway since L34's setting is not terribly
sensitive there anyway.

Yes, John, I too have found this to happen on occasion; not very often,
however. It has never been a worry or a bother.
