I suddenly found this mic in my locker, a coverted ADK A 51 to a Kludge Audio pcb. I modded this 15 years ago because of an article in Recording Hacks. Today I wonder what capsule this may be, it's seems to double side, but the two sides connected, might be done wrong. All I remember about this build is that it was difficult to get parts and info was little. And the tropical fish caps, are they 5pf? Black/green/black?
