Yes redo the PS and change the bias meter resistor values to change the bias level and make the 7591's last longer as pointed out by Dave @AK. Turns out the Fisher bias mark is at 21 watts which is 115% of the tubes capability. It was worse on the X-202. He calls the two serial tube killers. Nice thread linked below. Thanks as always for chiming in. Do you know Jim McShanes site for non Citation II stuff or do you just inquire there? Thanks in advance.
