Robert, the HF44 having a lower melting point than the rib solder is great info!
I had the same thing happen, both the lug and the barrels were still tinned so I just cleaned very well, fluxed with pure rosin and put the torch to it with the barrels plugged on one end, tilted and filled with water past the lug area.
I was VERY nervous about loosening the surrounding solder though.
One thing I noticed, both John's and my example seemed to have very little of the available mating surfaces actually bound by the solder, led me to think it was a poor repair come undone?
Nice tip.
Mark
