If it`s still available BAKERS soldering fluid, but I would think any ACID type flux would do{don`t forget to wash off after otherwise it will corrode} Last pro team I worked for we used Super Glue Gel & a push on plastic end cap on the cable end { i think you can still buy the plastic end caps they are a tight push fit & can be re used, but we used to renew each time. IIRC we used get them in bags of 1000 a time}Way2many":tih8xfuw said:Any name of flux you can recommend...fleabat is throwing up the usual 100's of useless hits!
