I seem to recall the late G3VA reporting in > the Bulletin that he had lost an AVO 8 that way. Reminds me of the Samsung Netbook PSU / Charger. Whilst it doesn't produce any QRM that I have noticed there was a debate on the user group about some users getting tingles from the exposed metal sockets etc. Some felt it some didn't, one user said if you don't believe it try licking the silver trim round the edge of the case, err, no thanks. On the scope I measured the often seen huge induced AC ripple from these dirty beasts. Eddie G3ZJO
