Yup - it's a CG-305 - verified it this morning. Odd, though - Someone else said that the output was High voltage 2400-1750-0-1750-2400VAC, DC voltage 2000/1500, 300 mA continuous yet the critter is labled (engraved, even) 3500 and 4800. That's -gotta- be across the entire secondaries. Half of that (what you get when you measure from CT to outside winding) fall exactly half of what the transformer has engraved on it. > CG means "commercial grade".

I'd appreciate it, Don. I'm reasonably sure the previous post is correct, though. 73 = Best Regards, -=Jeff/W5OMR=-
