heater voltages

[Smeggy]

Toob n00b alert!!

Is it detrimental in any significant way to run heaters at 12 and 6V instead of 12.6 and 6.3V?

I'm running a 12V 3.75A regulated supply from an old monitor and it works and sounds fine but wanted to know if there was anything I need to be aware of doing this.

No.
