I am attempting to duplicate the power supply offered by AES. In terms of the A supply electrolytic, how high a value should I aim for? If someone has the schematic for this supply that would be great too.

Brian, I built this power supply years ago and not have schematic in hand but mine had a 4700 mfd electrolytic in the A power section. Do not have means to e mail u schematic.

Here is one I found on the internet:

Take those 3 diodes out which are across the output. The resistor marked 56 ohms should be a pot, around 1000 ohms. Setting of this pot determines output voltage.

Use a large value filter cap. Higher is required when you need more current. Since AES used 4700 mf that would be min for operating 1920's radios. Use 10,000 or 20,000 mf if you have one.
