H740 Bridge Rectifier

Hi Allison: I have the schematic in front of me, mechanical drawing too. It's on my web site if you _really_ need it after this, or send me your fax number and I'll get it to you that way. Looking at the mechanical drawing, if you look at the rear of the 8/f, with the H740 installed, the bridge rectifier is at the top, right hand side of the supply, above the large heat sink fins, to the right of two large transistors. Ascii art for pin orientation: (top edge of board, as you face component side with H740 installed) --------- | + AC| (Large Trans) (Large Trans) | | |AC -| --------- ----------------------------------------------------------- ----------------------------------------------------------- (Heat Sink Fins) ----------------------------------------------------------- ----------------------------------------------------------- (Large Trans) (Large Trans) (Large Trans) (Round connector) (bottom edge of board) The rectifier is labelled only "NSS3514", no ratings indicated in the specs, just "bridge rectifier". Input is 28VAC. Good luck, Kevin --- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca
