just received two of these connectors. great quality, threads are super smooth inside and out. Super fast shipping, you do need to be careful soldering the positive lead on, its easy to melt the insulator... mine still works, just got a little melty...![]()
It is best to disassemble the unit to solder the positive lead on so that you do not apply heat to the insulator. The pictures on Varitube's site shows the unit taken apart and the end cap and the spring slide up on the wire for the soldering to be done for the positive lead to the positive pin. You can then reassemble the parts after soldering.
