Most repair techs use lead solder, just better to use.
We switched to lead free where I work almost a decade ago, these days I only ever use tin/lead if I am working on valve equipment.
Once you get used to it the modern lead free solder is just as easy to use as tin/lead and a lot less toxic!
I agree. I use a temperature-controlled iron and SnCuAg solder. The small amount of silver lowers the melting temperature and prevents tin whiskers.
But 60/40 or 63/37 leaded solder flows and wets better than the above.
