Note: If you are not 100% certain of your skills, do not attempt to work on SR&D Rockman circuit boards. They are among the most unforgiving I've seen, and will damage easily.
Vertically mounted electrolytic capacitors should be positioned/soldered 1/16" to 1/8" over the circuit board.
1. Purchase some 3M two-sided sticky pads from Home Depot.
2. Poke the leads through one of the pads and trim to match the circumference of the capacitor.
3. Stage the capacitor into position and secure to PCB using Kester 63/37 solder.
