The stray resistor leg was one still floating around after clean-up - I have been building electronics things on and off for about 45 years :)
I had enjoyed the kit for about 24 hrs - and, through lack of self discipline, was listening to 40m on the QCX while cleaning up :) - a discarded lead was accidentally projected into the air and down onto the kit.
Thanks for reiterating the issue of meter voltages and their potential to cause damage. I typically use a CRO first and should take more case with the meter.
Interesting to note that for my cheap "Micron" (no-name) meter, I measure the following voltages across the probes for the selected resistance range settings:
