Apparently, I'd consolidated my good stuff into a pile some months previous, and subsequently forgotten where I'd stowed it. I was quite pleased to rediscover that pile today. I came across this little drawing (about 8cm wide) that I'd forgotten all about, and I thought, that little doodle needs to go on the blog! Transistor talk. PNP parlay? Something like that.
Incidentally, my challenge was successful, even though my "sketchbook" was all B-grade stuff. Yay getting-by!
