10 gauge power cord. Too much power for tube amp?

@moonwatcher power cables have mediocre connectors and stranded wire for flexibility soI like to go one size bigger on my power cable than the wire in the wall--except my dedicated circuit is 10 awg from the breaker box so I use 10 awg power cords.

@carlsbad2 yes, if you have a dedicated 10Ga service from your junction box then no reason not to use a quality power cord having the same gauge. (10Ga on average has about 36% less resistance than 12Ga for the same length). But the differences we are talking about over a 6' length are in milliohms. 

@moonwatcher indeed milliohms (or less) and but we are talking about milliamps or less but they are changing over a time of picoseconds....how does this all add up?

It is beyond my detailed understanding of electricity and if I didn't have a full time day job and several hobbies I might do some experimentation.  I am a physicist with esperience in national labs.  

Instead, I tune my understanding of what is going on to match what I hear.  and while I'd have to admit it is all theory at this point, it supports the facts.

Take care,

Yes, it's like using Cardas copper in interconnects (which I've read many science labs do between instruments). It might be overkill, but who is to say that using the best you can doesn't make a difference? Enjoy.  I love the idea of a dedicated 20 to 30 Amp connection from your junction box. I live in a rural area and am lucky to have fairly "clean" power, at least for now. 

I have an Ayre power amp that would go into protection mode at times, I found out it was a certain rectifier tube if used in my DeHavilland preamp.  Changed recifier tube and the problem was solved.
