If you are using tube rectification, then it isn't necessary. For solid state rectification (and large value PSU caps) then it will help to eliminate the initial power-on "slam" as the transformer and SS diodes are briefly looking into what amounts as a short circuit, as the bulk caps are at zero volts. THe additional few seconds of "warm up" time that the CL-90 offers, will act as the electrical version of a vehicle's shock absorbers.
In a tube-rectified PSU, the lCL-90 really doesn't add anything useful.
