Hello,
all I do know is that Rohde released, some years ago, a
"capacitorless" power supply.

One that doesnt give spikes :-))?
Any supply with feedback linear or switcher is a potential
spike producer !
?
I am not up to date in this area
it is possible that slow-start supplies might be best. Other
members may have more ideas.

OK, I'll bite--
What kind of power supply would you recommend?? I always
thought that a regulated supply would be the safest.?
Were these linear or switcher supplies that produced the
spikes?
Thanks,
Dave

During 10 years or so doing
life tests on transistors in the 1960s and 70s I would not
use regulated power supplies for powering the devices
during their life test. When asked, I demonstrated the
switch on pulse with a Tek storage scope. ok it was only
microseconds wide but peaked at the unregulated level.~35v
.....enough to damage 24v transistors.This can also happen
with a transcient load. It is to do with the bandwidth of
the feedback loop.
