I have one or two suggestions.  Increase your fire
insurance policy to the replacement value of your home
then go seek professional electrical and psychological
help.  Power supplies are not batteries.  You run the
risk of unbalanced loads in each supply, harmonic
coupling from transformer quadrature, and without a
sophisticated current and voltage regulation system
you will never be able to balance the load to each
supply.  Sell some of them and buy a sufficient power
supply for your amp. I don't mean to be harsh on this
but it is a bad and dangerous idea.
