<div dir="ltr">I don't see any power regulators in this pdf. What regulators are in the unit? I see +/-15 and +5 supplies being called for. Is it regulating a +/-18 supply into those three voltages?

I have a dynachord pdd14, but its power transformer is no more<br>
working. I can't find out its properties, neither the whole gear<br>
schematics.<br>
I have only the one attached here.<br>
Could somebody help me finding which kind of power transformer i<br>
should use ? I think somethink like 220 to 18 &12V should be ok, but<br>
not sure..<br>
<br>
Thanks per advance !<br>
