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?

For example, 10 awg is a larger diameter than 12. As mentioned previously, when you check the outlet’s wiring, make sure the ground wire is firmly connected. If you have an outlet tester, use it. If you aren’t using a high quality outlet like Hubbell, now would be a great time to install a Hubbell hospital grade outlet. Most 20 amp circuits use 15 amp receptacles unless it is a dedicated circuit. Hope you don’t need the amp repaired.

If the panel has 20 amp breakers, then the wire is probably 12 gauge. If the breakers are 15 amp, the wire is probably 14 gauge. This can vary by local codes and builder. Some builders try to save money and use both 14 and 12 gauge based on the intended use.
