I'd imagine Youtube would be useful for soldering tuts. Practicing on an old/dummy circuit board would be very useful beforehand.
You'll be pleased to know that desoldering a cap[acitor] is much easier than a pot[entiometer] - A cap only has two straight legs to desolder and pull out, whereas a pot has six and they're all bulky and kinked!
Kit you'll likely need:
* Low-wattage soldering iron, with a fine tip
* Soldering iron stand (to rest the iron while it's heating up)
* Wet sponge/paper for cleaning the iron (of any old globules) before tinning the iron tip
* New capacitors of the correct specification
* Solder (not too bulky/thick) with flux
* Solder-sucker (to remove molten solder when you're de-soldering the old cap out)
* Wire cutters or similar, to trim the capacitor legs to length after soldering them in.
Low-wattage soldering iron, 15 Watts or so, is useful to avoid burning things. A fine-tip on the iron allows you to work with greater precision, some tips (sold as default) are a little big and bulky and unsuited to circuit board work.
If you take the ribbon cables out of the main board to separate the chassis away from the front panel, make sure you remember which ribbon cable goes to which socket as there are three ribbon cables and they all look identical.
PS > And another thing! Will the Ti|3 have user customisable/importable wavetables?
A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
