I could tolerate 85Hz well enough. -- spammage trappage: remove the underscores to reply Many people around the world are waiting for a marrow transplant.

What about compared to sleeping with two women? Nuclear physicist Edward Teller said the average man received less radiation from nuclear power plants than from sleeping with two women. More importantly, how well does that work as a pick-up line? (Teller didn't say)

Been working with em,' and TV sets for a long, long time ..... and still here, at least I thinks so :D Monitors a health safety eh, you wanna be repairing some of the older Philips TV sets with their PD500 EHT shunt stabilizers, a triode valve operating at 25KV... that put fear of God in many an engineer .... cos it's a genie in emitting X rays, this is used to stabilize the 25KV tube supply to stop ballooning etc with variations of beam current.... these models were soon 'scrapped heaped', the problems dies with the advent transistors and X ray protection circuits over voltage sampling. CRTs, be it TV or monitors do emit X rays but they are well within the required level to be ignored plus the fact the screens have X ray protected coatings as well... and for RFI radio frequency interference the better quality monitors are contained in screening plates and boxes, more so around the CRT tube and base to prevent interference to radio users say.... not so with CRT type TV sets where the tubes operated at a much higher EHT voltage. davy |
