Parts list indicates the (2) Jensen JT-OLI-3 are included in the full kit. They weren't included in my kit, and they're described as optional in the Assembly Instructions. I'll probably order some next time I order from Jensen, or make them myself, they're fully described on Jensen's site. Since I'm not using super long cables or capacitive load, I jumpered them.
Would be nice if all options/choices were enumerated on the schematic, optional transformer hookup, jumper settings, isolators, etc... and version numbers tying the whole documentation package together: assembly instructions, schematic, parts list and board revision would be nice, too.
