Hey guys I'm in the market for a good bench power supply. Something I can safely use to power diodes that doesn't have voltage spikes and whatnot. What do you guys think of this one? https://www.ebay.com/itm/MS3010D-30...726628?hash=item3412fad064:g:zXsAAOSwJQJddbfG

Please let me know what you guys would recommended.

I have one similar to this, but the one I use more may not be available any longer. It is the 5 amp version and has a button for low current that the newer ones and this don't have. I went to the trouble of dissembling it and cleaning all the switches and pots to keep them from becoming noisey.

Yes, but mine has a button between the knobs for high or low current. That is a blessing to have as you don't need that much current when you are binning diodes by wavelength. It also allows me to switch to high current mode when I do need up to 5 amps, but only at low voltages, below 10 volts.
