Default Re:diodes checking (magniciter )

I know where I can get used magniciters, but I would have to make sure the numbers are the same. They swap all the onans that come in to power-tronics.

^ No one in the shop understands Magneciters, so it's easier to swap in a Power-tronics regulator?

The shop that has the used ones told me they just change all of them that come in, they said they scrap them all.

They are old, obsolete, failure prone, expensive as hell, hard to understand for a lot of people?

Besides, who would describe a power-tronics unit as fragile?

Any unit with a magenciter is far too old to consider reliable power for anything. All the other components are old and rotten waiting to break, even the windings and varnish and such.

Sure they are fun as a hobby but this stuff has a finite lifespan until it becomes just too old.

The mistake people make is buying new junk to replace old quality. New quality is what they should have gotten.

Typical moron mentality. Even though superior elegant simplicity is staring them right in the face, they destroy it in favor of crap because it's easier than actually learning about what they're working on. Not technicians, parts swappers.

I do not entirely agree that old alone qualifies something as unreliable. More like the number of operating hours. But even that alone does not quantify the life of such things as electrical insulating varnish. Seems that the majority of generators spend most of their operating hours at well below rated load. As insulation temperature decreases, insulation life approaches infinity.
