I can maybe bring you some 2399/5998 tubes, one of the best there are. I still have 3 pairs for sale ;-) (pm me if you're interested)
Now about the power lines. Don't overestimate this. If you live in the Us with a bad powergrid in a city with 10.000.000 people in an apartment block with 20 floors and 500 apartments, you might indeed not get good power.
In europe quality is much higher and you can easily use an extension cord in stead of the wall socket (unless you have a really bad grid or an oooooold house). I'm not saying a good power cable doesn't do anything (Mine are being hand made as we speak) but the effects are minimal around here imho
