Hi,
I just purchased a B60RPH C series and I do not have turntable right now. However there is a 60hz hum when I output the phono section. I have completely isolated the unit, disconnecting all inputs as well as the speaker connections, listening only through the headphone jack with the B60 plugged directly into the wall.  I have tried several outlets on different circuits in the house with no change in the hum.  I was expecting a quiet, phono white/pink noise type sound through the phono input. Am I missing something or is there a problem with the unit. Thanks for any advice.

Hi

Do you have anything plugged into the Phono Section?

No, nothing is plugged into any input.

Hi James,
Thanks for the quick response.  Sorry for my curtness in the previous post!

No, nothing is plugged into any input.

OK so i am thinking that without the ground the table would supply is the reason for the hum.

Hi,
I found an old pair of shorting plugs but one must be bad. I can eliminate the hum in one channel with the plugs in and when I switch plugs the hum stops in the other channel. Problem solved?  I'll have to get my hands on a turntable to confirm. Thanks for the guidance.
PS. I can't believe i found those old plugs! I can' t remember what I did 5 minutes ago. Priorities I guess.
