Its been awhile since I've silver brazed anything, but I use a silver brazing tip on my oxy-acetylene torch set. I have 2 different heat melt silver brazing wire, I have map gas, but as I recall it wasn't up to the job. But you are correct Jim, I've ruined a few pieces with to much heat.

MAPP gas and acetylene copper to copper....brilliant.
It just takes a couple of seconds too long to melt/slump brass when its brass/copper or brass/brass.
