Power Supply design for multiple modules

Some advice would be apriciated.
I'm placing multiple modules, relay boards, relay volume controls and preamp pcbs in a chasis. They require multiple different voltages.
24VDC
12VAC
12VDC

Can I take a 12-0-12 transformer and tap off as shown in the attached? (Caps etc not shown)
I'm wondering if the common ground will cause an issue?

🙏

So the idea, It's going to be a collection of modules running off a common supply.
1. Relay driven preamp input selector (No power on the signal path) 12VAC (rectifier on PCB)
2. Relay driven Stepped volume control (No power on the signal path) 12VDC
2. Single ended jfet RIAA pre 24VDC
3. Single ended jdet Buffer Preamp 12VAC (rectifier on PCB)

So I need 12VAC, 12VDC and 24VDC available
All PCBs will have a common ground through the signal path.

I've attached a more detailed drawing of my idea for the PSU.
I shouldn't be grounding any AC.

Thanks so far!
