ac cables falling out of IEC inlets on amps

I had the same problem. Use Blutack. DO NOT USE THE GENERIC GARBAGE, OR YOU WILL BE SORRY!

First, I rolled the Blutack [you will have to kneed real Blutack to make it pliable] into a "rope" about the diameter of a pen, and cut this "rope" to fit around the outside of the power cord plug. I pressed the power cord very firmly into the IEC, and got essentially a removable "putty joint" between the plug & the IEC. Depending on your power cord termination, you may have to press the Bluetack into the physical connection. of the cord pug & IEC. Be sure to hold the power cord in place for 20 seconds to let the Blutack "set-up". The Blutack should form a seal between the two...make sure that the outside if the plug & the IEC are clean and dry before you start [clean with isopropyl alcohol...90% or greater, if you can find it].

Tho generic stuff is much tackier and pliable than Blutack. Removing the generic can be a pain, especially if it is exposed to heat. It will turn into a sticky gooey gum like blob...trust me, I found out the hard way!

Man, I guess that some Audiophiles are REALLY anal. I am using a very heavy power cord on my tube preamp, which sits on the top shelf. The weight of the cord will pull it out just enough to create a problem with the right channel.

The Blutack fix is cheap it works, it's removable [it's been in place for 2 years with no slippage], it doesnt require a major project involving time & money, and as others have suggested, it might even dampen vibrations.

Watch Apollo 13 to see what can be done to improvise a solution [the CO2 scrubber problem]. Sometimes, even a rocket scientist doesn't have to be a rocket scientist...just a handy-man with common sense!
