Your schematic shows that you could use 2 in, 4 out, if I'm reading it right. That is, the center taps on the two secondaries are not connected to anything, but the photo is blurry. What seems wrong about the transformer I found is that it can be connected to 120 volts or 240 volts as the primary voltage, but you want 36 volts for the primary and (2) 18 volt windings for the secondaries. That is so unusual that I don't know what to do about it.isn't there just a simple 2 in 6 out,

Your circuit is making a +/- 15 volt supply. So the windings need to be separate.The secondary is dual 18v-9v-0v, 18v-9v-0v. The 9v winding (center tap) of both secondaries is not used. So i'm guessing that means the transformer could be replaced with a dual secondary 18v-0v, 18v-0v. Not even a center tapped transformer, so i could look for a dual 36 volt non center tapped transformer... Am I understanding this?
Is there a Hammond version of this? How about TE electronics. i found this.

That would make sence. I guess that means i could use my MOTM modular synthesizer power supply in place of the EML power supply. That's +15 -15V as well. Pretty standard modular synth power.Your circuit is making a +/- 15 volt supply. So the windings need to be separate.
You could use a 36 volt center tapped, but you would need to modify the rest of the circuit significantly.
Yes, that would work. or 2 what they call wall worts would also work. You may have some laying around. Most people do.That would make sence.

What about using two single secondary winding transformers to supply the +, -? Not practical, but would two transformers work?

I've heard about the two wall warts, haven't tried that yet. How about this hammond transformer? It's dual primary and dual secondaryYes, that would work. or 2 what they call wall worts would also work. You may have some laying around. Most people do.
Perfect!I've heard about the two wall warts, haven't tried that yet. How about this hammond transformer? It's dual primary and dual secondary

Are you sure your transformer is bad? I'm not sure I've ever seen a bad one, and I'm getting really old.I've heard about the two wall warts, haven't tried that yet. How about this hammond transformer? It's dual primary and dual secondary

Awesome! The original transformer works great. It's for a clone I built this winter.Are you sure your transformer is bad? I'm not sure I've ever seen a bad one, and I'm getting really old.
That would work, except you said earlier (#4) that the transformer had a 36 volt primary.I've heard about the two wall warts, haven't tried that yet. How about this hammond transformer? It's dual primary and dual secondary

Ah, my mistake, its not 36v primary, its 115vThat would work, except you said earlier (#4) that the transformer had a 36 volt primary.
Who are you talking to and what do you mean by "calculate its voltage"?But how to calculate its voltage.
