Class A

No! If you have +65V and -65V and the output at 0V (as it should be), with no signal, each transistor has just a bit less than 65V because of some losses. The 63V is fine.
Nelson was thinking your 65V was really +32.5V and -32.5V.
You DO realise that several days of posting were wasted just because you're too lazy to post a schematic?

You should also read up on class A, because the voltage across the transistors has nothing to do with that.
Do your homework, Google is your friend.

Thank you. I am with the others:
Class A/B. Or "B".
2 x 65 V are very unusual for Class A - exept you would use 2 x 15 powertransistors, or so on;-)
Your psu had to give > 1,2 kW continuous;-) There should be a trafo-power of > 2,5 kW, as example;-)
You could set the current bias as high as psu and heatsinks perform;-)

ok thanks for the infos guys, so i need current settings to make it in class AB
