[Phil G4SPZ]

I was given a Marconi TF144H/4S signal generator. As it came from a fellow radio amateur, and was described as ‘working’, I confidently plugged it in but found that it was apparently dead. The mains lead went in via a Plessey 3-pin military style angled connector, which on investigation had been wired with earth and L swapped over.

My consumer unit had no RCD protection then. However I never felt a tingle despite touching the (live) metalwork several times. Rubber soles on a dry carpet and not touching anything else saved my life. I no longer trust anyone or take anything for granted!
