JD9 output capacitor modification question

Hi All,

I have purchased new Clarity Cap MR's and sat down for a serious look at how to install them.

My question is how to deal with what appears to be a three handed job - one to hold the capacitor in place, one to manage the solder, and one to hold the heat element.

Obviously I am not a pro - what am I missing and/or what is the trick to complete the mod without screwing up the circuit board?

Thanks, Dsper
