Granted if you go through Parts Express, you do have to get by the
"full sonic potential" phrasing of their website.... (Cause you know

Parts Express has some cheaper 2% stuff, but IIRC, the 575 manual
specified 3% Ag solder, since 3% wasn't available, I figured 4% was
better than 2%. (It probably didn't matter much though.)
