So after beating the shit out of this stupid TI power supply (none of your suggestions worked, thanks) I come to find that it does have an internal fuse and that it is complete intact. Wonderful. This thing is shot beyond repair at this point. It wasn't intended to ever be opened apparently. Anyway, hopefully I can figure out what this pile of garbage was supposed to be putting out. Of course, there are no markings on the housing of the transformer. There is an IC in here. It's inline with the hot side of the input voltage. The markings are thusly: UMI EI X25 150(degree symbol)C 2.5A 250V~ A varistor? Anyway, this is a heap of junk now. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
