Hi Chris,

Yes, that occurred to me after I sent the email. I think this belief was 
planted in me many years ago, perhaps at technical college - can't 
remember. I'm pretty sure it was true once though perhaps the rules were 
relaxed when SMPSUs came on the scene. Any  VK old timers have a similar 
recollection? Have I been exposed to too much RF?
