I'm after a new power supply. My Thurlby ones take up way too much space and they have coarse, fine control which is annoying the crap out of me if I'm honest. Also none of them are tracking.
I am after something like an Agilent E3630 really but I want to buy something new and they're discontinued and too expensive anyway. Unfortunately everything you seem to be able to get now is either ridiculously expensive, has a noisy fan in it, blows up after 5 minutes, has horrible transients or is made of poo. I don't need LXI or fancy programming ability or even anything 10 turn pot wise. Just enough to set to 10mV resolution, 2x 20v outputs tracking with digital readout. Something I can short out and just leave it there without it burning the house down.
Are there any pieces of gold I've missed in my search?
Should I just wait for an E3630 to appear for a reasonable price?

My GW instek GPC-3020 has tracking and cost me around $50. Unfortunately it also has the loud fan problem. That said its easily fixable - meaning to do that one of these days..
I would be happy to test it in any way you want me to- maybe to see how close the two outputs track.
Other than the (very) noisy fan it appears to be good quality and the output is quiet enough to work fine powering SDR equipment.. I heard my first (very weak, low power) 10 meter beacons using this power supply as the SoftRock's power.

I'm building my own :)

I'm missing the new Keysight E36312A and E36313A on your list. If you don't need the accuracy then the GW Instek GPE-2323 would be my next choice.

They're both off my spreadsheet because of the fan and smuggling them past SWMBO,
I'm closing on an E3630 so far. I can get one for £200 cash from someone I know who just bought one expecting more amps for the money.
