Don’t feel bad. I soldered the high quality ceramic tube socket to the wrong side of the board on the E80cc preamp kit. I had to clean out solder from 9 slots on the board. I used a one hand operation de soldering iron I bought from Amazon. The iron heats up and melts the solder and then I push a button to release the plunger and the solder is sucked up from the area. It did a beautiful job of cleaning out the socket slots on the board. $12.99 to $39.99 on Amazon. One hand operation! All the best to you! Brian
