K3 Speaker Resonance

[Roy Morris-6]

My K3 speaker performs flawlessly and puts out wonderful audio until NR is turned on.  It then produces some shrill resonances at some frequencies.   I find these resonances disappear when using NR on external speakers.  I owe an apology to Lyle Johnson for blaming the problem on noise reduction parameters.

the same problem here, and yes it is a resonance from the speaker and the
K3 cover. When I find time I'll have to add some rubber washers or so to
calm it.
