How well does the CL90 work?

I'm thinking of using a separate filament transformer so that I can warm up the heaters on my expensive NOS tubes before I hit them with SS rectified DC. How well does the CL90 work? Does it prevent "stripping"? I'm not exactly sure what that is but it occurs when full B+ is applied to a tube whose heater is not fully "warmed up".
