Using the middle tab as ground reference here is what I get
Q2000:20.30
Q2001:-18.93
Q2012:voltage is get pulsing up and down
Q2010:-13.71
Could Q2012 be defective or would something else cause the voltage to be pulsing leg 1 is -13.37 volts put leg 3 is where I get the pulsing voltage

You use ground when checking those.

The transistors series pass transistors used with a shunt regulator input. They are not IC regulators like the L7x15 regulators.
The first leg is the reference voltage.
The second leg is the supply voltage.
The third leg is the output.
Q2010 and Q2012 are in parallel. If you didn't get the same voltage on them, you had a bad connection. If replacing only one brought the amp back into working condition, it's likely that you had 2 defective ones.
