[HECnet] Re: LA120 PSU fault (fwd)

I believe that the prints for the H7150 are in the Field Maintenance Print Set Manx DECwriter III LA120 Operator Reference Card, 1978 LA120 Technical Manual, January, 1980 LA120 User Guide, May, 1984 LA120 Field Maintenance Print Set, October, 1979 On Sat, Dec 28, 2013 at 2:15 PM, Cory Smelosky <b4 at gewt.net> wrote: Afternoon, I've managed to acquire an LA120! Woohoo! However, it had some issues...as was discussed when I got it. ;) I've replaced the blown fuse, the there is continuity for the pico fuse on the PSU...but I have no idea if that indicates it works or not. The only thing that runs is the fan. What are some test points I can try? Also...what is the value for the picofuse? I have 125V 1.5A fuses...but I think it needs higher current. I tested to see which voltages are preset: +5 -12 -24. No +12 or +24. Anyone have full schematics for the H7110 PSU, or know enough about it to help me debug this one? Alternatively, I can get an H7150 for $95 on ebay. Can an H7150 be tossed in an LA120-AA? -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
