Just snagged one of these on eBay. Sold as-is, it arrived with a power light working, but no output. It needed all the tantalum caps swapped out. Found 3 shorted ones, one on each of the +5, +15, and -15 lines.
Almost all were the 4.7/25 blue ones, which got replaced with 35V units. Handful of other values scattered around, as well. A couple nights on the bench and almost a hundred new caps later, the unit now pumps out video! Nice and stable, and looks picture perfect on a WFM/vectorscope.
Is there a .pdf of the manual available anywhere? Particularly interested in adjustment procedures for the circle roundness/size, as it seems a bit off.
Anyone know the type numbers for the power supply rectifier diodes? Mine look a bit toasty. 2 different types. I figured I could just use 1N5408 and 1N4007, but just curious. Would like to see the schematics for the different options, as there are several unpopulated BNC cutouts on the rear panel, and several areas of unstuffed PCB.
Mine has a "400-01 Video Swemar Unit" installed, rather than the multiburst. Is the multiburst actually a plugin? This thing is hardwired into the unit, doesn't look to be user swappable.
