Aloha fellow listeners, esp. Klas and Telinga users--
While travelling down a rocky Kaua'i stream bed last week, I and my Telinga
Stereo took a dip, submerging the dish long enough to get all of it very wet.
The Zeppelin around the mic's was saturated and trickling water. The mic had
been on record-standby. I immediately disconnected the cable from the
accumulator to the back of the mic's, removed the dish, expelled some water
from the zep by centrifugal force, and brought it home to dry out. I carefully
avoided switching the mics on.
Back at the ranch, I directed a hair dryer at the mic's, on low heat at a
distance of 18 inches. After about a half hour of this I connected the system
and tried switching the mic's on. The right channel sounded clear but the left
had an intermittent unsteady flutter/rumble. I then pulled out the pipe that
feeds into the zeppelin frame so hot air could get in to where the capsules
reside. Another 20 minutes of drying cleared up the left channel.
One benefit of this mishap was to clear up a mysterious problem I had been
having, and for which I was about to send the mic back to Sweden for repair.
The flutter/rumble on the left channel had been an intermittent problem for a
few months, and was apparently due to high ambient humidity, a common condition
here in Hawaii.
I have a concern that corrosion may be prone to develop in the system from this
wetting. Any advice, Klas or others?
Mahalo!

Subject: Re: Telinga survives drowning
Thanks for telling, I love storys like that. I have a number of them.
After a few weeks, I film team in Brazil had only one mic working - the
Telinga. Then they dropped it into the water, and everybody said "no, this
was the last microphone!" But it dried up in a few hours and worked again.
I don't think the rumble you have is due to humidity. Telingas have been
used in Borneo and Malaysia rain forrest for months, without making trouble.
If the Telinga now works as before - with the rumble, we have to look for
other causes.
It happens rarely that a transistor is faulty when I put it in, but that it
shows after some time, months or so. It is sometimes called
"pop-corn"-noise, which can be described as rumble. Are you using phantom
power? Then it can also be a leaking capacitor.
Are you using the Twin Science mic? If so, the rumble might also be natural
rumble from the cardioid. The cardioid is much more sensitive to handling
and wind noise than the omni, which may make you believe that there is
something wrong.
Thanks again and let me know on beforehand if you send the mic.
Perhaps you should, as the risk for fungus on the membranes now is probably
higher, as they have been in water.
Klas.
