| "Tom Del Rosso" <fizzbintuesday@that-google-mail-domain.com>: May 03 08:16PM -0400 The switch mechanism cracked in my magnifying lamp. No ballast. Just a momentary and a latching switch combined, that feed the 4 terminals on the tube. The equivalents I find are around $20. Must be a cheaper source. Physical shape doesn't matter much, since the hole can be enlarged. Thanks. -- |

That's a special purpose switch that combines the function of a glow-starter and on/off. Not a common hardware store stocked item. I've an old 15" tube desk lamp like that and it has an inductor (coil) ballast in the base. Are you certain yours doesn't have an inductor or electronic ballast? I've never seen a fluorescent lamp fixture without one. As for the bum switch - one alternative to a new switch would be to wire in a glow switch, space permitting, and replace the defective switch with just an on/off one. You might have to extract the glass envelope glow switch from its plastic or metal can. You'd also have to determine the current rating of the required glow switch. Sincerely, -- J. B.

Sincerely, A ballast is inevitably present. NT |

I had to replace the switch on my bench magnifier lamp (long ago swapped-out lens with an ex-epidiascope bulging lens for bigger mag), normal switch. Does have ballast in the base and a starter "lamp" but I wonder if excess current makes the switches fail more than usual. |

The Wikipedia URL has the channels. However, to get the sub-channels, you have to fish them out of the "Notes" column. Unless some station gets creative, the sub-channel numbers should be the same on the RF channel and on any translator. Also, to the best of my understanding, if a station is capable of transmitting DTV using ATSC encoding, it is also capable of transmitting HDTV (usually in the form of MPEG-4 AVC. It may choose not to do so for some reason, but in theory, all DTV stations can belch HDTV. >PVR software I posted some time ago in alt.os.linux.slackware. >That software turns a hdhomerun (under $100) device into a cable >cutting video recorder. Most metro areas in the US has some video fanatic that maintains a current and up to date directory of what the various TV stations are doing. With spectrum reallocation and incentive auctions, such a list is needed unless you want to scan for changes regularly. No clue who does that for Smog Angeles. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
