Re: ecc83/12ax7 with 6.3v heaters for phono?

That seems to be what the remark has in mind. "okay" is up to you. No damage should occur, but I expect you will get some hum. You'd be a lot better off running the heaters off D.C. You can certainly start with A.C. and if the hum is unacceptable switch to D.C.
