Hi Guys
Silver solder is terrible stuff and should only be used if everything else is silver plated. Silver loves to react with oxygen and needs a lot of heat to flow properly.
A guy with an electron microscope told me about watching electron flow over and through different metal interfaces; that is, where two metals are in contact and a current is present. When all the metal pieces are silver the electrons flowed fairly smoothly, but was extremely erratic if any piece was replaced by anything nonsilver. he said there is no benefit to using some silver here and there; the entire path needs o be silver including transformer windings. Otherwise, the minuscule benefit is not attained - very expensive to chase that portion of a percent change.
Just look at how silver tarnishes.
"Eutectic" refers to the ratio needed for direct transition from solid to liquid mix and is the 63-37 I mentioned above. But get it with JUST lead and tin. Rosin core of course. Multi-core makes no difference and is more for marketing.
