      I suppose a shaved down toothpick would do the job equally well.

      I use a stainless steel sewing pin from my wife's sewing kit to clear the small holes.  The pin  has a plastic ball on one end and has a diameter just a bit greater than the component lead diameter so it provides clearance for the next lead to go in the hole.  Sometimes it is a bit of a pain to get the old lead out but pushing one the end of the lead to be removed with the pin in conjunction with soldering iron heat has always worked for me.

      Sorry about the small hole sizes and the problems people have had with the present version of the circuit boards.

      I do hope the kits are fun and useful.

      I've replaced 3 without difficulty. No one else has raised the issue as far as I know.
      Finding that some pairs were not closely matched, a number of guys have replaced them.
      What was the difficult part of it?

      Having put together a couple of different kits now, my impression is that the SMD soldering is child's play compared to the tiny annular ring size for discrete transistors. I haven't found it a problem for initial build, but replacing a bad BS170 can be a real strain. Has anyone else had a similar issue?

      Tony, would it be possible to use a slightly larger layout pattern for the discrete transistors?

      Thanks for your consideration,

      Brent, AB1LF
