The lead is in the solder. It is 37% lead. This is a HUGE issue in electronics and the new no-lead global initiative is called RoHS. You can do a search for it if you want more info. I have to deal with this issue everyday. Europe has become very serious about it.
To be honest, many amps made today still use SnPb solder. I do too in all the electronics I build. The current RoHS solders aren't fully tested yet and in my experience, they don't flow nearly as well and wet with difficulty. But eventually, everyone will have to switch over.
