Hey Brian, If you only have one AC adapter plug you could try it on the Cary AC cord first, because that could cure the hum as well.
Brian, sorry--I got you mixed up with the fellow who first posted the question. Anyway, I was referring to AC plug adapters, not RCA jack shorting plugs. Sorry for my confusion.
Yo Commodore, You can pick up the 3-prong AC adapter plugs ("cheaters") at any electronics store, even Radio Shack. Some supermarkets, drug stores, discount stores like Wal-Mart, Home Depot, or any hardware store--really just about anywhere! These things are very common. :)
Hi Brian, The quickest and easiest thing to try in addressing the ground loop problem would be to inatall "cheater plugs" on the amp's AC cords so as to float the ground pin. You can pick them up for a couple of dollars if you don't have them on hand. I had the same problem with the SE 100s and the "cheater plugs" cured it instantly. Good Luck!
Hey, Ralph Nader, thanks for that hair-raising anecdote. I think we can agree that it's certainly tragic when good beer goes to waste. :) I guess I'll just have to install a dedicated earth ground for all my audio gear. If your heads-up prevents just one more drop of beer from being spilled then... Sniffle... I'm sorry, I just can't go on... Thank you and may God bless! Seriously though, you raise a valid issue. People do get struck by lightning, win the lottery, and get shocked with the potential to be badly injured from touching improperly grounded gear during major malfunctions when current shunts to the chassis.
Not meaning to beat around the Busch, but are you sure this guy didn't spill a little beer into the powered-up amp before he touched it? How many did he chug down anyway. I have to apologize for my indefensible flippancy, but I've always held that drinking and critical listening don't mix--and this is just another classic example to support my case. :)
Commodore, I'm glad that the cheater plugs worked for you! Now if you ever suspect that an ungrounded amp is on the verge of melt-down (major failure) don't touch the amp, pull the rubberized plug out of the AC outlet instead and let it cool before handling. Enjoy your Music. :)
