A fellow AK'er has a Sansui 7000 that he'd like to repair and restore, so I said "sure! that'll be fun!" After looking a little into the specs, parts and history of this big 70's receiver I found it is a high power cap-coupled design... so *I* had to buy one, too.
So, now I've got two units to repair (both have the two output transistors in one channel dead), then recap, and, at least for mine, upgrade/mod to modern parts. This thread is just a record of the work.
@DCinDC has compiled a master thread of some good info as well as written quite a few posts on his own. So, there is plenty to help with this. http://www.audiokarma.org/forums/index.php?threads/the-master-sansui-7000-thread-link-thread.443893/
Once all the boards have been cataloged and compared to the schematic, and after a couple of orders of parts have been gathered and installed, I'll post a BOM for the results. Note: Both of the units I've got on the bench are the large-tone-board variants. If you're following along for your own unit, you'll need to determine which variant you have before using everything from this thread. http://www.audiokarma.org/forums/index.php?threads/sansui-7000-a-tale-of-two-bothers.369638/
