I got a better solder station to test this out with some old Ken Rads that have issues. I tried it with a smaller solder iron and it just wasn’t working well. Hoping to have some time this weekend to try it out.I remove as much as I can and then I use WBT 0800 silver solder. I do not say this lightly, but the difference is alarming, but if you think about it, much of the solder was done 70 or more years ago.
@ColSaulTigh did a reflow tutorial video I think? Someone did one on here. I watched it once and now I can’t find it.
