At NSA I use a Lynx Studio Technology, Inc Lynx 1 card. Very nice. Both
digital and v good analogue inputs, all XLR (Cannon type) plugs. It does no=
t
connect directly to an internal CD burner within a PC, so use the external
digital inputs on the card to connect with a pro CD player if copying from
your CDs.

I used a 4.7 uF mylar on it tonight. One on each mic. That got the
current draw, but not the oscillation. I have a spare mic, so
experimented with that and exchanging with one mic seemed to get it all.
However, I then went out and recorded both with and without the MP2, and
all recordings still have a whine at 1.73 kHz. And it's in both channels.
BTW, with that value cap I'm getting more low end than I know what to do
with. I'm picking up the gas turbine power plant 3 miles away as a
steady rumble. And airliners for far distances. The power plant can be
heard by ear, so I'm not surprised to pick it up. If I put a tight notch
filter on the 1.73 kHz whine, the rest sounds very good all up and down
the scale. Putting the Portadisc's 175hZ high pass on does barely take
care of most of the low output. I'm beginning to wonder if I'm going to
have to build in a high pass in the enclosure. The MP2 also could not
fully tame it. These mics definitely pick up the low end well.
Without the voltage drawdown the overall sensitivity is up a little. I
did crank the voltage down to 6 volts tonight while listening, and that
had little effect on the output. It's not very sensitive to supply
voltage. Anything inside their spec is going to do fine.
I did got out with the MKH60/30 MS setup and record a bit just to make
sure it was not the Portadisc or something. That's got no whine, nice
and clean.
I'm assuming the output transistors must still be good, otherwise I'd
not get signal. That leaves me hunting through a whole bunch of tiny
caps, a few resistors, and the two coils at the output end of the
circuit board. Though it would seem the coils being bad would also stop
the signal. The caps all seem rated at least 15 volts. It's a exercise
in reading tiny print. The resistors are very tiny, so low wattage. I
think they will be my first suspects. Sure wish I had a circuit diagram,
may have to sit and make one. Only thing in common between the two mics
is the battery, I split them off immediately. I suppose I should try
running a 2nd battery and see if that helps.
