Title: heater elevation and tone
Post by: 12AX7 on November 14, 2016, 11:15:38 pm

Is it possible that in elevating the heaters some 30v could affect an amp's tone in any way aside from less hum?

Just been finding that the tone seems different and that was the only thing i did since that happened that i haven't changed back to pre issue.

I've never noticed any difference in tone on the amps I've built with elevated heaters.  :dontknow:

Can you describe what sounds different?

Never heard of tone changes with elevated heaters

maybe something happens if previously your amp was in "danger" zone due to excessive voltage between cathode and heater ???

I don't know

Ok, thanks. I didn't think so but just wanted to eliminate that so i can get on with the process of elimination.
