Memorex Power Center
Added 2019-12-05 05:11:13 +0000 UTCThis was something I picked up a little while ago because it put a smile on my face. It's not the most exciting video but maybe it will appeal to some people like it did to me.
This was an effort to get a lower production effort video out before I had to go out of town. I think I covered everything I could about this but there isn't really much that's all that exciting about it. It's just one of those things that feels right in a computer setup like this to me.

Ah, that makes a lot more sense! I was moving a bit fast on this one and they looked for all the world like poly fuses. Being MOVs matching that schematic makes a lot more sense. Thanks for pointing that out, I'll make a pinned comment clarifying that. I, uh, might need to stop using my old ones. They are all flickering and I've been having some massive grounding noise issues where they are. I'll have to see if turning them off fixes that. The other ones I have seem different, the bulbs in them are larger and off center in the switch. I think this one I unboxed here might be a newer revision(the box is copyright 1995) that does have LEDs because the light elements seem a lot smaller than my others. I'd be curious to see if it does hold up over time but I'm going to baby this one and not leave it plugged in all the time so I'll never really know.

2019-12-05 14:15:16 +0000 UTCThe blue things are likely MOVs, metal oxide varistor. Poly fuses (PTC) would be redundant with the circuit breaker. The idea is that the MOVs will pass over voltage to to neutral and both to ground, thus the there of them. Every normal surge protector is that, this one could be considered "premium" due to the dedicated breaker which either gets omitted from modern TVSS, or "intergraded" in to the main power switch. https://www.electrical4u.net/wp-content/uploads/2018/11/varistor-3.png The indicators in the switches are tiny neon lamps. With lots of hours of use, they'll start to flicker, and irk any HAM friends. Neon indicators are cool old tech that hardly gets used anymore. Easier to drive on main than LEDs (only needs a single resistor). They can also act as a TVS (not in this application) for higher voltage by being a spark gap.
