I recently purchased the DPS-750RB A model, which is also shown as a
HSTNS-PD18. Using the instructions on YouTube, I easily changed the voltage to
13.9v. I haven't had time to look for RFI using an SDR, and certainly won't
have as extensive a test setup as Gary does.
I did not try to adjust higher than 14v, though that might be a good
experiment. If I had any confidence I wouldn't damage something by doing so,
I'd be willing to try higher voltages :-)

Thanks Gary. Do you know how high V+ can be set? Some radios, notably
Elecraft rigs, have lower IMD at higher supply voltages, with 15V max.
