Any battery out there can do +/- 24v?
And this is for my old linestage. Mine has Belleson regulated power supply there, and would to try Salas low voltage supply for that, in case no battery is available for this application.

That will be 4 x 12V batteries in series with the middle point being 0V. Terribly complex and heavy way of doing things but it is possible when the room is well ventilated and conditioned. What to do with the filaments? In series to their own 12V battery?

If the current draw is less than 200mA the new SilentSwitcher is an option as it can be set to +/-24V output. You only need 1 battery or alternatively USB PD power bank.
If you need + and - 24 Volt, you can make a bipolar variable power supply like this. Schematic is given here:

OP already has a regulated PSU. First post, first and third sentence.
