    Thank you, all, for your views and comments. My conclusion is that Fleenor's equipment is worth its price. I subscribe to the old Russian adage, "I'm not so rich I can afford cheap things." I certainly found a lot of "cheap" out there. For the long haul, I"ll put in a Fleenor splitter. Roy

    MFL DXH / Enttec D-Split 70575 / Fleenor 125

    I'm not very good at effective searches, but I did look unsuccessfully for a related topic. I was sure this question had to have been discussed in the past. Not finding any, here's my situation.I am slowly (understatement) bringing our small stage's lighting into the 20th century. I replaced...

    Vintage Lighting Mk V Scrimmerette Information

    Thanks to all of you here who have been so helpful. These old Mk V Scrimmerettes are now history. I've tried in vain to trace and piece together a useful schematic and board layout, but cobble a schematic together. I have to say that heat and age have taken their toll. I've had to repair and...

    Vintage Lighting Mk V Scrimmerette Information

    Alan was one of the first people I talked with when I started on this. I also got a LOT of help from John Dziel. Thanks for the steer to Lightronics and ETC. I'll start a conversation with them. You guys are great. Just knowing that when a tough problem comes my way, I've got someone to...

    Vintage Lighting Mk V Scrimmerette Information

    Well, I've tried for 3 years to find replacement parts and fix this unit, but I know it's a dead end. Parts are obsolete and hard to find, not to mention finding or making an extender board to test and troubleshoot it. We're running on only 6 channels and we're dead if it goes out. It's time...

    Vintage Lighting Mk V Scrimmerette Information

    Sorry to be so long to get back on this. Here's where it stands. I replaced one of the diode rectifier packs and it appeared both sections of the unit are working about the same. I don't really know if both at full power or if both are at half power, but they were about the same on the test...

    I agree with your observations about grounding the unit. I just wanted to be sure there wasn't some legitimate reason for letting it float. To set your mind at ease, I am a electrical engineer and have worked in the field on multi-phase aircraft power. I work with a power utility engineer who...

    Vintage Lighting Mk V Scrimmerette Information

    Thanks, John, for the information. Ours is a 2-phase unit - the board is even marked as such. The schematic is quite useful, so thanks for that, too! Your troubleshooting link was also helpful. I will let you know what I find.The date under the logo on the board is 1979. Can I assume that...

    Vintage Lighting Mk V Scrimmerette Information

    I have two Mark V Scrimmerettes. First, I am looking for manuals covering these units. Second, one of them has a problem on the Phase-A dimmers: they only go to half power. The other half of the dimmers work properly. I suspect the control circuit power on that phase. Does anyone have...
