C3m (=18048) Telefunken West Germany - nos tube

C3m is A.F. and R.F. Special Quality low noise pentode. It was made for the German Post Office. It is almost a perfect creation. This valve is a triple mica type. Additional mica is placed between the upper mica and getter to reduce getter material contamination on the upper mica when the getter is made so that the leakage current and noise will stay at a low level.
