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.

This is more suitable for a Class B or AB PA amplifier. Forget class A!
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;-)
No, frying tonight!Not going to end up well, no way.
My Krell KSA 50 clone with 3 pairs of the same transistors, + and - 36v rails and the .6amp through each requires a massive fan cooled heatsink to keep the TO3 cans below 70C.
