Indeed. Also explains why they are popular in some tube mics wired as
triodes - Sony C800 IIRC, he

** So YOU actually own one of these US$7,800 mics - dickhead ??

Reckon the Peltier cooler and that sexy heat pump might be the secret of the
" warm " sound ???


ROTFL !!

I wonder why they have wired it as a triode - you'd have thought they
would want it as linear as possible. Also, they have a very attenuated
bias voltage feed for the capsule.

All very odd.

The usual reason given is headroom plus probably the more tolerable 2H
distortion at high levels in a triode rather than the 3H you tend to get in
pentodes. ISTR this mic is specified to handle 150dB SPL - quite why you
would want to do that I don't know but with that level of sound input you
don't need a lot of gain. How this affects the performance at much lower
signal levels, especially noise performance, is another question.

Idiot. If I had meant that I would have written "I wonder why they
wired it as a common cathode".

Now - lie still. It is nearly time for the nurse to turn you over;
don't want bed sores, do we?

Most are kept in the mic cupboards of well-established studios some
of which have owned these mics since new. The ones that come
up for sale (and that is very rarely) are snapped up pretty quickly.

As I mentioned to Patrick, many tube mics, that were converted to
FET in the 70s are now being converted back again:-)

Some well-established artists come to studio sessions with their
own mic (often an early Neumann M47, M40, M50) and mic
preamp/compressor.

I can see you don't do much studio work Phil:-)
