I have a quick question. If I were to use this at +/- 18V, could it handle the continuous power draw of 2 F5 amplifier boards?

The F 5 needs about 1.3A, with +/-24Vdc (not sure why I used 18V). That is continuous current, though.

the F5 will draw up to 2.6A pr ch.
1.3A at idle and up to the point it switch to class B.
but yes. it can be used on 2ch of F5.

I had a quick question regarding this module. How do you set the output voltage to be less? I know that you just have to put a resistor in parallel but say I wanted +/- 25V what value would I put in parallel?

I would also like to know this. Is it possible to soldier in a pot here? If so what would you recommend?

What I've found is that... you can determine your new output voltage by using the following equation...

45V / 82.6kohms = new voltage / new equivalent resistance.

Hello s sorry for the late reply.

Please look at the schematic below:
Click the image to open in full size.
the feedback network is formed by R24//R20 + R11 and R21//R25 + R22. Voltage on Pin14 is 5.0V. The voltage on Pin15 must equal to pin 16. R20 and R21 is actually 82.6ko. It's not quite complicate to calcualte the value of R24 and R25 with this conditions.
