...the rest of the house is two-wire, with three-prong outlets that are, in the words of my electrician, "just for show."
There seem to be lots of problems with my electronics, spanning different types of components and different configurations of gear. The CD player's power transformer gets burn-your-fingers hot after a few minutes of routine operation, the preamp makes an enormous bang if unexpectedly disconnected from AC, the power amp makes a transformer hum in both the speakers *and* through the front apron, and the DVD player makes its own kind of bang, totally at random, during playback.
Some kind of power issue, as a root-cause? Other thoughts?

you might try these components in different outlets in your house to see if it does the same thing get hot ect.Im not an electrician but it would be nice to find an outlet that doesnt mess with your components.then the electrician could trouble shoot better?

You have had an electrician check out your home wiring? Let's just say the problem is no where else. Let's just say for sake of argument that it must be the electrical system. Now, what could it be? You have overheating electrical components and other symptoms, physical symptoms. Let's set aside the music becoming unlistenable for now. What defects in a home electrical system would overheat things? Some of the things you describe might be from a really bad ground loop. Something in you home may be dumping alot of DC. I don't know myself but by focussing on the electrical system you may get some answers here and elsewhere. I think you need to get an electrician to troubleshoot all the legs of your home electrical system. The lack of a modern ground system may play a roll. The voltage in your home may be wrong.
I'm just brainstorming. You said you are tapped out financially but it seems that that electrical system needs to be checked again. Are you having trouble with any appliances? Computer?
There is a cause for this problem, it's just showing up in your audiophile components. It's a clue that ALL of your components have symptoms. The overheating (if it is actually unusually hot, maybe it should be hot. See what I mean? No assumptions) is a clue. Let the facts and only the facts guide you. Write them down.
Of course, I know you've said that you've run your system at another location. I just don't see how the interaction between your components could be so bad as to cause these problems. (Assumption on my part, not knowledge) Another poster mentioned that this may be a problem in the neighborhood grid. Does this problem show up in any other stereo system?
The main thing I'm saying is to be very rigorous as you try to diagnose the problem. Make no assumptions. This is a real puzzler.

Would it make any sense for me to post some pictures?
