PREPARATION You will need a clean, dry and well lit workspace in which to assemble your kit. If possible, try to find somewhere where the parts can stay undisturbed in case you do not finish the kit all at once. It is a good idea in any case to split the work up - say assemble the circuit board one eueninn_tben.tffst jt. and put the case together the next evening You will need these tools (a) A light electric soldering iron, say 15 to 25 watts with a fine tip {b} Fine gauge solder with resin flux core; NOT acid flux. (c) A pair of sharp sidecutters. (d) A 'Pozidriv' screwdriver with a No. 1 point. (e) A medium size ordinary screwdriver and/or a 4B A spanner.
