Need to adjust the speed every time I turn on turntable

Okay here's another thread where obviously mijostyn and clearthink want to talk about things other than audio, so I'll exit here. I guess these guys are really amused with themselves.

Cleeds, As I recall, from reading those very same history books, Edison promoted DC electrical transmission. It was Westinghouse and Tesla, who had left Edison, who promoted AC. Edison infamously electrocuted an elephant in order to demonstrate that AC was unsafe.

Exactly. That’s what I wrote. Edison promoted the electric chair to warn about the dangers of AC. All of Edison's early electrification work was DC, such as in NYC, where he ran some of the wires himself.

Sorry for a bit of nothing, but you wrote, "AC is not safer than DC - that was Edison’s argument...."  I interpreted that to mean that Edison argued that AC was safer than DC, which we both know was not the case.  I had a feeling you merely made an error in syntax, but I just wanted to get it straight. Now I see how you meant it.
Just think: If Edison had won the point, we wouldn't need rectification in our audio equipment, but on the other hand the DC voltages available for B+ would in many cases need boosting. Also, it would have been difficult to assure that everyone got the same DCV at home.

@lewm I see now that what I wrote was completely ambiguous!

If Edison had won the point, we wouldn’t need rectification in our audio equipment, but on the other hand the DC voltages available for B+ would in many cases need boosting.

We’d be in a different world if Edison had prevailed, for sure. For one thing, we’d probably be paying a whole lot more for electricity. I think the main reason AC prevailed is because of distribution efficiencies.

Oddly, solar electricity is DC. Edison would have liked that.
