C3M PENTODE DRIVER
Look at the two round plates above the pins.
The lowest is a metal shield outside connected for lower hum. The other is the mica. The anodes are open from the sides. This open c3m pentode is the best for finest linearity.

It allowed plate distance adjustments after the tube was assembled. This noncommercial c3m pentode was used already in DHT post tubes from the 's.
We are lucky to have a lot of the C3g version with the additional zirconium getter. All C3m we sell gave this double getter! So that is additional to the Barium getter ring or plate. A Zirconium getter is expensive and it works like this: A Barium getter has most of its function during the short moment a few seconds that it is flashed during production, so when it is in the tube in the form of a cloud, while being transferred out of the getter halo, and condensing on the tube glass. This cloud, at the moment it exists inside the tube, absorbs at that short c3m pentode almost anything whatsoever. Collection c3m pentode Hermann Fleischanderl A.

Would a zener be a good idea or not? C3g is a nice driver for DHTs but it is starting to run out of steam when driving a B hard so if you are maxing out the B then better to use the C3m Its possible to set the C3m up for a little less current but I wouldn't drop below 17mA anode current as Mark states. Frame grids generally give better quality tubes, though it must be said that the quality of C3m is just as superb, c3m pentode I make the statement here for C3g and C3m, that there is no better tube available of the same kind. If you think I am wrong, email me with facts from a data sheet, and if you find a better tube, I will add it here.
Generally with C3m and C3g it can be said they have the gain of a pentode, and distortion same as only the finest triodes like E80CC.
However C3m will give that low distortion at a gain of A gain of 78 It means you can drive a B with just one C3m, and you have less than 1V input sensitivity. In a few words, this explains why these tubes are so great for HiFi purposes. For applications like pre-amp tubes, or driver tubes for 45 or 2A3 the C3g can be used as well. They show their extreme c3m pentode distortion only as pentodes. They can be used triode connected, but then gain comes down a lot, and the distortion increases to a level just below triodes like 6SN7.
C3o is a C3m with 6. However C3o is exceptionally rare as NOS tube.
There is "S" Version of the C3g that is said to me to be selected for higher minimum transconductance. Quality won't suffer throughout this process while a guitar amp is configured in a casual or professional mode. Show More Show Less. Collection of Hermann Fleischanderl A. Thread Tools.
