A high performance tube should give you better signal to noise.
A non HP tube might give you a somewhat different C-field setting for
same center lock-in.
The physics of Cs-133 is still the same, and the RF-chain is still the
same. If not, someone has to teach me something new, or at least inform
me why the high performance tubes are so much different.
