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.

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.
Hello Bank738,
Sorry about taking so long to respond but I have been putting in extra time at work this past week.So far I have put about 8 hours on the Chinook so have a ways to go before it is broken in.I have played a variety of music and have been very impressed with the unit.Super quiet with wide,tall and deep soundstage,well-defined bass and very good detail retrieval.It is significantly better than the Belles 120A it has replaced.
