That was the first place I thought of adding resistance, but totally
external is better when you are experimenting. If this added resistance
turns out to work as a permanent solution for most cases, hopefully the
extra resistance can just be added into R21, allowing you to replace it with
a higher value - but I'd want Paul to look at it first.

Tacking the resistor to the switch is not desirable from a reliability
standpoint. Only 1 side of the resistor is mechanically supported, and
vibration from moving could eventually cause the resistor to fail. If a
person absolutely has to do a repair like this, you want to tack the body of
the resistor down with RTV somewhere (side of the switch, in this example)
to prevent vibration from cracking the leads.

It would probably work OK, but in your heart you would know that deep in the
soul of your beautiful MOTM system is a festering, cancerous, abcessed, jury
rigged slimy hack, and you would awake screaming in the night hoarsely
shouting "I'm sorry! I'm so sorry! I'll never do it again!! I'll fix you the
correct way right now, my beloved..."

Err, never mind.
