I'vebuilt five A12'S so far and they have all been about +-18v on both the negative and positive pin 3 and 5... Before twaeking the amount to +-16v Now this last one I made was at +-20 on pin 3 and 5 before tweaking.. On your instruction manuals it says I shouldbe getting +-14v
I looked over the last 4 pres i built and everthing looks ok... Any suggestions?

Double check the values of the voltage-setting resistors: R29,R30,R31 and R25,R26,R27, and make sure D5 and D7 are oriented correctly.

When you adjust it, what's the lowest voltage reading you can get?

That means you didn't do step 31 in the instructions (turn R25 and R29 full counter-clockwise), which sets the voltages as low as possible.
In other words, there's nothing wrong.
