Lisa 2 PSU (both versions) Component list?
Posted by: gavo on 2010-07-27 01:30:14
Hi all,

I've done a quick google but not come up with much, so I thought I'd be lazy and post here to see if anyone knew the answer. I've got a couple of Lisa 2 PSU's (both the low and high power varities) and was wondering if anyone knew of a reference that described the capacitors, their values and ratings, for the purposes of replacement. Both my PSU's went bang with lots and lots of smoke (very impressive) so I'm assuming I wont be able to read the values off the exisitng components.

Also, a repair guide would be nice 🙂

Cheers,

Check it against this schematic: http://lisaem.sunder.net/cgi-bin/bookview2.cgi?zoom=-1?page=16?book=6?Go=Go (Lisa 1?)?

Some references (the former about the Lisa, and the latter a DIY guide):
