I use them less now than I used to. I am active in another industry and have a pile of switching supplies. I have a couple with clip wires trailing out, so I can always get +5 regulated at 15 amps or whatever. And there is usually the -5 and +/-12 on those. I don't do enough work on DSP stuff to need a 3.3 in the bench at the moment. The DFX cards are usually just replaced. And on any other system I can usually use the system's own supply for 3.3.
Got a 12v reg on the bench for testing relays, motors, who knows what. ANd there are +/-15 and +/-12 supplies around, but I rarely get them out.
And of course Mr Variac sits next to me always.
There are those occasions though when I power some circuit up externally to see how it runs without other things being powered. Maybe to see a preamp working without powering the PA section.
But as a matter of fact, I just brought in a couple enclosures from the warehouse with the idea of building a +/- adjustable reg supply for the bench in one. Spiffy curved corner things with handles on top. 0-30.
I have not been doing as much design in recent years. That is where I used the bench supplies more than in repairs. Basic digital work and control interfaces for custom stage situations.
