I'm looking for any and all information about this mic. It's kinda like a K eagle but only has one tone. It has 20 db pad and vox as well, I can't get it to key up. I don't really have any type of schematic. It's a really good looking mic and I'd like to get any information I can. I have owned alot of d104 over the years and have never came across this. I'd put the condition of this mic at 8 of 10 . I'm very picky too I have never seen a 10.
