| 214188 | 2004-02-12 18:52:00 | Pheonix... you have it basically correct. The degaussing device... a 3 pin device is in fact 2 varistors, 1 a PTC and the other a NTC packaged in a single envelope. The PTC increases in resistance as you say with an inrush of current through the degauss coil. The NTC ( a high resistance cold) is effectively across the degaussing coil in parrallel, its resistance falls with current and it is there to maintain a current through the PTC to uphold its resistance and so limit any further current through the degaussing coil to an ineffective value. Bob... the mystery component, you say one end is connected to the degaussing device. Where is the other end connected to? Is it connected back to the AC input Phase or Neutral. Probably through a double wound inductor? Oh, and Philips domestic units do break down... frequently. I've made a good living from them. I shall not be around until next week to see any replies. I am being removed for the weekend by my family for celebrations. Today I reach 3 score and 10. Not sure what family are celebrating. |

| 214190 | 2004-02-13 02:05:00 | Yes, happy birthday Eric and many more of them. Just for the records, this "thing" is only two legged and has Mains on one side and the degauss coil on the other. That’s it. If it were to short you’d have the degauss coil straight across the mains and this is what initially worried me as it was testing near enough to a short circuit. Now I know why it has a slow blow fuse! :D |
