Possible to run 2 regs from same winding?

Using a single secondary winding for two supplies requires that both supplies have a common voltage. That is usually the Zero Volt ground.

All the downstrean circuits are connected to to common voltage. Be careful you don't create a loop around which interference current can circulate, else you'll get noise on any audio circuit that uses that loop as part of it's signal route.
