I wouldn't risk it. Look at the Astron SS-30M as a suitable replacement. It was rated lowest noise in a QST line up test some years back. I have two, they are small, lightweight well regulated and have Volt and Amp meters so you can see whats going on. The SS-30 is same unit w/o metering.

I am changing my supply for my ICOM IC-910H because my PS-30 is dying. I have an SGC PS-50 supply that is not regulated, per se, it is a huge supply with massive transformers. It appears to work fine, but I am worried about the fact that is starts at 16v or so.

Specifically, is 15.5 to 16v too high to safely run this radio and is a drop of 1-1.5 volts too much unregulation for proper operation?
