Just received me kit from Hayseed Hamfest and have a question in dealing with the twist lock legs on the original cans and the soldering done to lock them in place. I assume I need a flame thrower iron to melt that area and suck or wick it out. Job seems pretty straight forward except for this part. Any recommendations or tips would be greatly appreciated. Updated my 800C a few years ago and its still running the original cans but I figured it was time to update them as well so I bit the bullet and decided to do the job but admit it seems a little intimidating dealing with the soldered grounds.
