Loud pop when I use the turntable on/off button


I hooked up a new Manley Chinook phono pre-amp yesterday and when I press the turntable's on/off button I am getting a loud pop sound.The unit seems to be working,I need help with the on/off problem.I never had this problem with the Belles 120A that the Chinook is replacing.Turntable is VPI Classic One with Lyra Delos cartridge.

I have the same issue with my Herron & VPI Classic combination and I simply turn the volume down before switching off the table. Of course replacing the Cap is an option as well.
I have a transrotor fat bob TT with the same issue. I just flip the mute switch on my LAMM preamp first. But why would a TT manufacturer not provide a capacitor that would avoid this in the first place?
Jyprez, if it pops when you turn it on, it needs to be fixed. I am sure the manufacturer intended for a cap to be there!
My new C1 with my Zesto Andros PS-1 is dead quiet when turning on / off the table with the volume up.
