Pass on the diode type (although we may assume it is a silicon utility model). As to the soldering: _how_ hot do you expect it to get in there -- ordinary solder melts at, what, 300C+ ? <g> But if you do the job, try to use a temperature-controlled iron (eg Weller) and consider applying heat shunts whilst soldering. And, of course, use decent multicore solder. (Or am I teaching granny's grandpa how to suck eggs?) -- Andrew Stephenson
