Ok finally got the Vox board adjusted and hooked up the laptop power supply. I have about 19v on the PA and am getting about 9-10 watts out. Plugged in the computer this evening and was able to make several contacts on PSK31. Seems to be working fine my only concern is the PA is getting pretty warm even though it is heatsinked to the rear case. I will have to watch it closely and see what happens.A fan may be in order. Thanks to all for the guidance.
