I have never used it with a tube amp, however, i have used it to tweak a
couple chicken band radios and it is quite sensative...probably down to
about 0.3 of a watt...that is,the audible indicator will perceptively change
with less then half a watt of
RF change.
its not drastic, but it does change if you are paying attention.
