Help identifying FETs

B

I have an early (circa 1993) Rode large diaphragm condensor mic which is
getting a badly needed servie. I am trying to identify a couple
transistors, which I believe to be FETs. Problem is, I cannot find any data
on them at all.

The two transistors in question have the numbers:
3DJ7F
3CX5B

Do these numbers mean anything to anyone out there? I have tried searching
on the net, and the few on-line cross reference guides I can find, but I'm
drawing blanks. Rode only made a very few of these early proto-type mics,
and they don't seem to have any data on them.

Any suggestions would be greatly appreciated.

Bill Ruys.
