  1. ...because they build product in large batches in China. To keep back a small selection of every part so people can buy a single replacement pot, I can understand why they don't offer that facility, it would be very expensive and time consuming for them. They would much rather you bin the product and buy a new one and many people will. Good question about the more "pro" range products, I don't know, but I suspect the answer depends on if it's a bulk far-east product like M32 or one of the existing professional ranges which they have taken over.

    X32 Problem

    I replaced the PSU module in our full size X32 a while ago, it was definitely a custom Behringer module which I got from the UK spares place in Southend (I think that has changed now). There were no bangs or anything, it just lit the scribble LCDs dimly and nothing else happened. I didn't attempt to fix the faulty PSU module, although being an inveterate hoarder, I do still have it somewhere. Fixing SMPSUs freaks me out slightly as the potential for bangs is quite high, plus I hate faultfinding them as the nature of the circuit means that separating fault and symptom is difficult.
  3. They look like they use an array of 10mm LEDs which is poor for beam control and brightness so don't look great to me. Also appear to be only available in the US. I have some LEDJ 7Q5 (square flat things) which are good as uplighters but not mega bright and some LEDJ Performer 18 Quad which are quite poky and have a useful beam angle. Both fairly bomb proof, had one PSU module failure and was able to get a spare module from Prolight Concepts UK to fix it.
  4. Can't you disable the master mode or standalone mode on the fixture? This is normally an option, though often under some weird menu name. You could make a little circuit using an SN75176 chip to buffer the incoming DMX signal, that would prevent the fixture sending the other way, it would need a 5V power supply though. Pin 4 as shown below connects to the DMX+ output on pin 3 of your radio receiver device. Pin 5 connects to ground of both DMX and the PSU ground. (You should not generally decode DMX just by taking the DMX+ line and ignoring the DMX- line, but it will work fine in this particular situation of a directly connected wireless receiver) 1 8--- +5V +5V-----2 7--(to pin 2 of fixture DMX) +5V-----3 6--(to pin 3 of fixture DMX) ---(from pin 3 of DMX)-4 5---GND (to pin 1 of fixture DMX & incoming DMX)
  5. I have got some mains festoon with a connector like this, or very similar, so not necessarily low voltage.
  6. Yes Pulsar designed and built Clay Paky's electronics and software from Goldenscan 1 onwards.
  7. I suggest you download "ELM" from the Enttec website for testing. The demo version puts up a dialog box every 5 mins to continue, but it is really handy for testing this sort of thing. You can set each universe to broadcast or unicast and test for Artpoll response etc.
  8. I think most of the newfangled intelligent lighting from that era was assembled that way. Certainly I was involved with many of the UK light manufacturers at that time and they all did it like that - assemblies farmed out to various homeworkers then returned to the factory for final assembly by hand in small batches. Several of the UK manufacturers were spinoffs of metal fabrication workshops who saw an opportunity in the marketplace.
  9. No LED Par I have ever seen outputs a good white with RGB all on 100%. They all look pink. You have to program a good white in your controller.
  10. Interesting, I think it'll be the USB drivers that are the problem if anything is...
  11. That is what the weblink I posted does. XP VM using virtualbox. I have used that technique to get a USB EPROM programmer working so it'll definitely do stuff with XP-limited hardware.
  12. Ah you're right. clearly they sold the designs to someone in Slovakia! They must just be making the old designs though.
  13. We were involved with the design of the Chevin amps and Chevin Research has not existed for probably 15 years. Most likely fault for the intermittent channel is the gain pot failing. Also they had a weird home made optical limiter (LED and LDR in a heatshrink tube) which sometimes got muck in it. As Dave says the other is most likely output stage transistors, but that part of the circuit was a fairly conventional mosfet output stage.
  14. Go here and type "xciter" into the search box https://www.martin.com/en/support_downloads/download_types/software Software download is 10th on the list for me. If (having installed the software) you right click on the exe file and select "Properties" then the "compatibility" tab you can select to run it as XP or "run compatibility troubleshooter". This may or may not help depending on what the problem is. Alternatively you can fairly easily make a Windows XP virtual machine on a current Windows machine using these instructions: https://www.lifewire.com/how-to-set-up-windows-xp-emulator-for-windows-10-4772549
  15. He said 100x 1W G40 lamps, this is the classic LED festoon from China. Incandescent G40's are usually 15W or 25W.
