I have to build a LF amplifier stage working in liquid helium.
Those I found in the literature as CF739 (Siemens), SGM2006M, 3SK164 (both
Sony) are discontinued.
Does any one know some types available for this job?
Or even better is there a web page listing electronic components working at
cryogenic temperatures?
