TOKO Inductors Needed for EM Theremin!

[i]The plans call for a 12VAC power supply, so if I get the 12VAC transformer at RadioShack and follow the schematic shouldn't I have the correct values in my power supply part of the circuit, or do I need to do more than just follow the schematic?[/i]

The Hot Rodding the Etherwave schematic calls for 14VAC.

The only problem with the 12VAC transformer is the tolerance of the 12VAC. Since you do not require a lot of current you will probably be
OK. Test it before you solder it in your circuit so that you can return it if it doesn't work.

I read a little about rectification, and it seems that the theremin power supply uses full-wave rectification. However, the plans only call for two diodes to do the rectification, so that means that the transformer would have to be center-tapped. Will the RadioShack transformer be center-tapped?

I assume you are going to the RadioShack to get
the transformer so check for Five wires (2 primary, 3 secondary) and CT label.

There are 3 wires I think- 1 AC, 1 neutral, and 1 ground.

The transformer has an input and no output?
Not a very useful transformer ;)

Oh...I meant that it has an input of 3, and and output of 3. The input and output both have the 1 AC, 1 ground, and 1 neutral.

You should get the schematic for the transformer.
I do not believe any of the pins are ground.

It sounds like on both sides there is a
line, center-tap and neutral.

Is there a possibility that I could use an adapter that changes wall 120VAC to 12VDC and just input that directly into the regulators without the rectification part of the circuit?

You need a positive and negative DC voltage.
Also you need the earth ground.

The transformer, the two diodes and the two
filter caps are probably the lowest cost way
to go.

I feel like the transformer 12VAC center-tap, ground transformer that I need should be a pretty basic part. Am I looking at the wrong things or in the wrong places?

Is there any store that anyone could direct me to where the transformer that I'm looking for is sold?

As far as I can understand, what I need is a transformer with 12-15VAC output that has a ground and a center-tap. Is this all I need?
