By the way, we'll be happy to send out these surface-mount 1 uF  
capacitors (or whatever we determine is the best value) to anyone who  
would like to try the experimental mod, immediately and at no charge.

These are huge as SMD parts go. Anyone with a fine-tip iron would have  
no trouble putting one in. There's no need to take the original,  
smaller one off; you can just stack the new one on top.

If you're in a hurry, you could use any type of capacitor that will  
fit, including an electrolytic. Just be sure to put the (-) end at  
ground if you use a polarized capacitor.
