Good idea Wendy, I sometimes use my daughter's nail varnish to mark different hfe on trannies like BC456A/B/C. She gets lot's as unwanted gift's in myriad colour's, saves lot's of different bags; just have to mark the bag with a little key, EG red A, blue B, green with sparkles C.

"A really useful hand tool to have on the electronic workbench is an Otoscope." I agree. I got mine out of a hospital skip years ago. It's great for seeing in out of the way corners, checking down holes etc.

Polaroid glasses can help ID hard to see IC/tranny numbers too, just a matter of getting them at the right angle.

Andy.
