Zitat von David Riley <fraveydank at gmail.com>:
I may be involved in an effort to get one or two
DECSYSTEM-2065 (KL10)
systems running in the near future, and I'm seriously considering adding
quite a few voltage/current/temperature monitors.
Instead of all of that, why not
just replace the capacitors?
Why not do both? The monitors will help detect when
the new
capacitors inevitably start failing.
The problem is, they are going bad, because you didn't use them.
Monitoring them after switching on the power supply isn't not really
neccessary, as you can see the hole in the pcb very easily.
And a monitoring circuit to monitor a CAP in circuit is not going to
be easy anyway. Electrolytic CAPS are changing their capacitance
drastically over temperature, and actually the worst is, that going
bad, they are getting hot during startup, where you have the worst
ripple on the power line.
