Author Topic: Irem G-X50C Schematic Needed Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-10-2002 11:38 AM                     I have a G-X50 that will not light a lamp, only getting a flash. I'm not getting enough no load DC to make it happen, although the start circuit checks out fine. This is a 115 VAC 900 watt rectifier that is solid core, not the variable core type that most are accustomed to. I suspect I made a wiring error during re-assembly as it was shipped to me taken apart. Thanks! Mark @ GTS  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

Only running a 700 watt lamp in a Super Lum-Ex off of it...or at least trying to. I doubt it'll toast itself for the occasional use it'll get. One thing I'm not sure of is if its a 220 volt AC unit ,or 115 volt as the tag says. It behaving like its not getting enough primary AC yet the tag on the darn thing says its 115 volt. Needless to say it will be toast if I don't be sure on that spec! I e-mailed Irem to find out exactly whats up with the primary on this one. I donno, I've never had one of these models either but its sure built like a tank and has alot of filtering on the output for such a small rectifier.

Ricardo Croce is the man to contact at IREM.

I did find a basic schematic for it on the Irem web site so this may help. There is only a high and a low tap on the primary of the xformer, plus about 6 other taps at 5% increments....according to the Irem info. Will await to hear back fomr Irem to see what they say.
