Has anyone else here experienced this?  Do you just try  different Power Transformers out to see what you like best for the application?

I plan to use two power transformers, one for a dual rail regulated supply for ICs, another for a single rail supply.  I'll probably get up to 1A being drawn on the single rail when the mixer is all done, so I figured 2A or 2.4A will be sufficient spec wise.

For the tests I've been using one power transformer at a time to supply the IC and the discrete circuits.  From the secondary VAC it goes to a full wave bridge rectifier, made from 1N4007 diodes.  10400uF filtering, then goes to a 120ohm power resistor to bring down the voltage since the overall load is so small right now.  I split the main rail with two 30K 1% resistors and added a couple caps.  Referenced the virtual ground for the IC.

I can draw that up later if it would help.

I realize I'll likely be better off with a regulated supply especially for the ICs, but this is what I've been trying for now.
