Tubes can generate extra noise, a rushing or hissing, Microphonics, and other sounds deemed 'extra' and not desirable -
This is what started the Tube Testing practice.
Unfortunately, some of the sounds are 'normal' others are a result of age, and others still are the result of the circuit-
and Interconnect cables
Assuming that the unit was once quiet, and the interconnects have a ground shield that IS connected at each end, then we are down to tube age -
(Sounds like you have a Shindo Preamp - so I will presume that the circuit is good)
Do you have a spare set of tubes?
If yes, try them out if it regains its quiet condition - then that is the issue...
Happy Listening
