Use a noise-gate. That is more or less the only thing able to handle
this. You can do tons of service and adjustments and improvements, but
in the end you will still fell that it is noisy, because:
a. the acceptable noisefloor was way different in the 1970s
b. more or less all the components have drifted since the 1970s, and
you really do not want to swap them all out
c. a chorus is usually noisy because of the technique involved
So, yes: it is noisy with the chorus. I have one, and mine is noisy
too. Still sounds great.
