Help me to lube up


I am using an older HeadRoom Cosmic Headphone amp. I have to switch between 3 different systems quite frequently,

Unfortunately, the jacks are recessed inside of the back-plate, which can make unplugging the RCA's difficult [my fat fingers make grasping the next to one another RCA's a problem]

Can anyone suggest a CHEAP lubricant, which may facilitate removal? But I do not want to degrade the connection.

And any puns are more than welcome :-)

Thanks, Dan. But I have to use 3 different interconnects for the 3 systems, so your suggestion is not an option.

The problem is the tight fit on the headphone amp.
Is the problem at the headphone amp or system end? You could leave the problem end connected and detach the other end. Just a thought. Dan
