Heh, I think they want to fix it because it weighs around 270 pounds and it's a struggle to move around. I used to own the same model and it cost me $20 for a couple mexicans to dump it somewhere. It's from the early 90's and has a piss poor picture compared to even the cheapest lcd/led tv currently on the market. I think that one had the "teletext" service built into it. Got that one straight out of the Zenith employee store when they had the plant on North Ave and the 294. Was supposed to be a life-test set but someone really failed, even though it was supposed to have the "Premium Sound" package, it sounded like a $10 clock radio. A couple years on I opened the back for something and the entire sub-woofer amplifier module was missing. Just a couple connectors laying where the module went. Oddly enough the sub-woofers were there, just missing the amp for them. How they q/c'ed that for resale is beyond me. -bruce bje@ripco.com |

They should be REMOVED and NOT REPLACED! > Peter WIeck > Melrose Park, PA It's only somewhat related to this, but I have a precision drill press with a real goofy looking manufacturer supplied speed controller. I called them up about something unrelated and and issue of weird bursts in speed came up. You'd have no load on the motor and it would randomly start to race. The suggested fix was to open the speed controller and cut out a bridge rectifier that turned the AC output of the triac speed controller and just let the motor get AC. It worked fine after that. I'm not sure why they added a bridge recitfier in the first place, or why removing it made a difference but it did. The motor is pretty similar is size to a sewing machine motor, and the standard universal motor type deal. The whole controller is cobbled together looking so I can't even tell if they added the rectifier or the OEM did. I'm sort of tempted to try the drill press with a properly designed industrial speed controller (Dart Controls), with and without the bridge rectifier to see how it behaves. |

Unfortunately, I am unable to answer your question about the amperage of the 10v line. Good luck. -- David Farber Los Osos, CA |
