I just got a vintage 421 U5 and it worked fine....until I opend it up.
I had removed the head where the capsule is located to fix up a few dents. When I did I broke a wire down in the base (not near the capsule). So I removed the area down by the switch and re-attached the wire. It did not work, so I removed the switch area and saw that I had a loose wire inside there. So I opened up the switch area where the transformer and (I am guessing) the pad circuits are located. (is that what the switch does?). I fixed all the loose wires and put it back together. Still did not work. I removed the XLR and there was yet another loose wire, I fixed that and still know workie! At least now, I can touch a wire while connected to an amp and here myself tap at all the wire locations including up at the capsule, but still no sound. (touching the wire so I can here the amp buzz). I had not tried the switch when I got the mic, but now the switch clicks 4 or 5 times but then spins past the last click if your not careful. Every thing I do to this thing seems to be a chain reaction to the next area.
Does anyone have schematics or a mechincal drawings of the switch area? Is there replacement parts available for this mic? Is there a service center anywhere? I just bought it, and would like the darn thing to work....
Note to self...you don't know SHIT about the inside of a mic.
