Can A/c that goes thru a tramsformer share a "ground" with a D/c ground?

Hello again Next project and i need help with. I read that its a no-no to have A/c and D/c use the same ground if it is transformer less.
I am removing the 12vac that is powering a pair of 6 volt tubes and am replacing it with a19 volt transformer and a bridge rectifier and filter cap.
As i am using the original tube sockets i would rather not unsolder each of the tube terminals that go to ground for the heaters.
But is it ok to use the ground for the DC that the A/c from the transformer is already using? If i am not explaining it well enough please ask me
as i do want to do this right the first time. Thank you for reading.

It's common practice to use a chassis as ground for AC-powered heaters in a tube radio and share that chassis ground for the DC and signal circuits. This depends on the signal level found in that circuit. A mike amplifier needs high sensitivity to very-weak signal voltages. The heater connection for that one tube will sometimes have its own ground wire to prevent "hum" from leaking into the circuit. But a circuit with higher signal levels passing through it won't need that, and can share a chassis ground connection with the DC circuits without causing problems.

I think that's what you're asking about.

Yes sir! Thank you! I was pretty sure it would be ok, but i have learned long ago to ask of those who know much more than myself, Now i can continue and feel safe.
Again thank you!
