Have at it brother
Wantomake,
The single primary toroid has 330 turns of say 22-24 AWG mag wire. However, I'm going to use the old standby #20 AWG to finish the secondary on my two .
I would suggest you use the 660 toroid and wind over it for a secondary
with 330 tourns of #20 mag wire also. Just do a reasonable back and forth
right hand wind wherever it looks god for you.
The transformers in series are supposed to be balanced with respect to having equal turns ratio, but just for a preliminary trial the lower voltage
output from the 660 unit may not matter all that much. The dual in series hookup will give double the amperage output anyway. (Hope so.)
You said I had good results - here are the facts so you will know. The continued circuit through the two winds gave a total voltage output from open end to other open end of 2.0 volts. When I disconnect the line wire to just one of the toroids the voltage dropped to 1 volt - hooked it back up so two were in series again -bingo - back to 2 volts output again! For the other test of the out put I connected it to the Ground return - Remained 2.0 volts.
Normally when I would touch a low voltage AC indication to the ground return
all voltage indication would disappear- not so with this setup.
All of this noted info told me that first of all the voltage output was real,
secondly it told me that the two winds were just for illustration purposes and that the secondaries had to match the primary winds for a balanced transformer output - namely 120 in with 120 out.
Also it told me that the input was DIRECT power from mains and that the output was from MAGNETIC FLUX - the separation I was looking for.
Hope all this explains whatI foundout and what you can expect for youself.
Later J,
Clarence
