well when my connections are permanent, i will tin them all. this was a temporary test. the lengths on my spt-2 are not determined yet, therefore it didn't make any sense to tin them all and have to cut it. it takes 5 minutes to replace a triac as opposed to 15 minutes to tin 48 wires and waist solder when i know i am going to cut them again. when my show is running and connections are permanent, it will be done right the first time!
