How about schematics without voltages 

Why do you think this happens?

(I know...to keep people like me from working on stuff)

That's when you use it as a learning moment, look at the components and see if you can work out what it should be.
Otherwise it's your opportunity to test it and figure it out by yourself, sometimes the only way to learn is to do it the hard way.
Have the capacitors in the power supply got a voltage rating ? the voltage will be less then the rated voltage, op amps have a max voltage so you can look that up as well.
It can be very tedious but if there is a will there is a way.

This is why many older schematics is covered in handwritten notes, someone had to do it the hard way.

Yes sir that makes my day hearing from you     

That's it really at least I can see how everything is connected

This hobby is suddenly getting much harder and I see that as a good thing it's time to man up go off and take measurements and draw conclusions and track things down 

Like when I was in scouts I got tapped into the order of the arrow and the requirement was you had to go off into the woods overnight with nothing
