Hi, Barry and group,

Kester 44 60/40 @ 1/16" (.0625") works best for me.

Additionally, I've got a nearly full spool (15.8 ounces) of Redring RX90RMA solder, 63%sn/37%pb, .8 mm (.0315"), manufacture date 7 Jul 92.  It's surplus to my needs.  If anyone wants it, please contact me off list.

My gratitude to all those who have served.  You have my respect.

To change the subject slightly, what kind of solder do most of you guys use?  I've run out of my 1lb spool and looking to get another.  Is 63/37 eutectic better than good old Kester 44 (60/40)?  What rosin(s) have been better.  I think I understand that some rosins are water soluble and wondering if those work as well as the old standby.

I assume most folks use diameters in the 1/32" to 1/16" range, correct?  I know much larger might be inconvenient for old radio repair use but are there any real advantages to smaller (like 0.020 or 0.015) except for SMT, etc.?

Anyone try silver solder?  I know it's used a lot in Tek scopes, etc., and haven't seen it much in old radios but was wondering.

Yeah, I know "it's just solder" and pretty much any good non-acid-core will do but thought I'd spark some new conversations.

Thanks guys,
