I'm trying to buy some quality solder, a desoldering wick, and liquid flux if I need it. Basically, I am just replacing some caps in my HRD 410 but am struggling to find exactly what I need.

What do you look for when buying a wick? Do I need liquid flux? Do you physically dip the wick in the liquid flux? Lastly, what is the best solder to buy?

Our local Ace Hardware store stocks the most common soldering equipment and supplies. I favor braided-copper ribbon wick and flux paste. Rosin-core tin/lead 60/40 solder is a good choice for most electronic applications.

Caveat: soldering is kind of an art. Really, best to practice on a discarded circuit board, before going to your amp.

I've used Kester solder for decades. 60/40 lead-stuff. All kinds of diameters, depending on the applications. For circuit boards --- prolly go to 21 AWG diameter.

Recently, I've used Wonder TRT (leaded) solder for boards. Really works well with flimsy stuff being put into amps, these days.

As for flux-rosin. I like Cardas:

Get a good quality solder wick. It'll save you hassles and time. I now use a Hakko 808 desolder gun. But, you don't need to invest in one of these unless you are going to be doing a LOT of amps.

And for circuit boards, I use a Hakko FX-888 station. You need a soldering iron WITH a heat control. Boards & components are damaged from overheating during the soldering process. If you buy a cheaper iron, be sure it has the option of getting different tips. Small tips for board use. Bigger flat tips for P2P use.

MOST IMPORTANT THING --- clean the area to be soldered. Cloth with a touch regular isopropanol works fine. Put a lighweight alligator clip (as a heat-sink) onto the body of solid-state devices, small resistors, and small caps (esp disc caps). These are sensitive to heat and can be damaged by over-soldering.


Good luck! Keep the practice idea in mind.

You don't need that ; electronic solder have rosin core inside.

Electronic solder 60-40 with the proper resin core;
