Question about building a variabale voltage power supply using 2 HP HSTNS-PL11

I have 2 HP HSTNS-PL11 power supplies I am planing to wire in series to produce 24v output.

I would like to be able to adjust that voltage output. I have found a number of different circuit diagrams and instructions online but I've found none that are capable of handling the amperage output of these power supplies (75 amps).

Looking for instruction on how to build a variable voltage circuit that can handle the amperage...
 
To elaborate a little further. These are 2 server power supplies. My idea is to use them as if they were transformers. Transformers that are outputting good clean power so I'm thinking the large filtering capacitor wouldn't be needed and that I just need to build a voltage regulation circuit that can handle 75 amps...

Google out how to join them in series ( disconnecting ground output from protection earth), it's quite a common mod. As of security - there is a reason the output ground terminal is earthed...

I sent you a link describing how to regulate them by changing the feedback voltage. The link deals with a slightly different HP model but the PSUs are similar. If not, sell your pieces and buy the other ones. They all cost the same, very cheap. I have about 10 pcs from our old HP G5 servers, lazy to sell them, enough room in storage...
