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

Tube amplifiers tend to be sensitive on incoming voltages. Is there a chance a bigger gauge power cord like 10 gauge may not be a good thing?

My amplifier tends to shut down occasionally upon start up. maybe moving to a higher gauge might be better. Does it matter?

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.

Just a bit overkill. I mean, your own house wiring from the junction box is only 12 Ga.

(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.
