DCC-116 E / DATA GENERAL NOVA 2/10 / Nixdorf 620 - Restoring and restarting

After the mess, ... http://actingmachines.com/classiccmp_forum/mess01.jpg ... it was time to reorganize a cool place to continue this restoration :-) http://actingmachines.com/classiccmp_forum/calm01.jpg http://actingmachines.com/classiccmp_forum/calm02.jpg Without the schematics of the two power supplies, I decided to follow the tracks on the printed circuits boards from the area where I measured the collapsed regulated 5vdc, I start to check the components and try to understand the problem alone, I decided to check the 5 big capacitors this one is a little bit high but OK http://actingmachines.com/classiccmp_forum/capacheck2.jpg YES ! I finally found a dead one, hourra!! :-) http://actingmachines.com/classiccmp_forum/capacheck1.jpg A 23000?f 15VDC used in the filtering of the regulated 5vdc, but... finally no, unfortunately ... it was not the source of the power fail :-/ Tomorrow I continue my investigation and I will check the big capacitors of the other power supply in charge of the 15V which is monitored and possibly also the cause of the error message.
