Radio cleaning and pre-emptive cap. repair?

My comment about flux..........I notice some independent folk are selling Kester 1544 on egag. What they are doing, is buying Kester in bulk (1 gal minimum) and repackaging. Some of those are not bad prices. A gal is something between 89-100 bucks plus shipping, so that's over a buck an ounce. So figure from there. They have to make something, buy the bottles, etc. A couple of ounce bottle will last a long time.

I use the crap out of that stuff soldering the buss bars into the drive modules at work
