You wont get more than 14.5 out of one..
Theres a pot inside on a small board that you can up the voltage but dont expect more than about 14.5 or so.....
I know this because i tried to get mine to volt higher and it didnt work....

If you dont know what you are doing DO NOT open the case on that pwr supply!!!!! There is voltage inside that WILL KILL you!!! Send it to Astron to get the adjustment!!
I speak from experience, as I THOUGHT I knew what I was doing, and woke up 3 days later with 2nd degree burns on both hands!!

Ol spacey is correct...

Only a less than wise person places his digits anywhere near the high voltage.

Only trained techs using the proper techniques and tools should adjust high voltage.

BUT I am curious, why does one need 14 volts when 12.6 is only a volt dot 4 away?

I've heard this before with regards to computer PSUs, but the description wasn't clear. Is the primary voltage in a switching psu higher than 110/120 US after going through the switching circuits and before being stepped down?

I always thought the danger was due to the higher frequency they use. The info I've found on the net doesn't clarify much either.
