[sdiy] Radio Shack solder.

[Jason Proctor]

for best results use organic solder - eg kester 331 (iirc) - for your 
resistors, caps, ICs, diodes, and transistors.

if you go this route you MUST wash your board in lukewarm water, 
ideally rinse with distilled water, and dry with paper towel (do not 
leave to dry) every hour or so (and again when you finish the above, 
obviously). the flux in organic solder is really nasty and corrosive, 
but if you do this there won't be any flux left on the board at all. 
the boards look really great. it's worth the hassle.

then switch to no-clean or rosin-core (eg kester 44) for the 
trimmers, pots, power connector, wiring etc. of course, don't wash 
the board when you use this stuff. once you switch to regular solder, 
you have to stay there.
