Edit: Meant to say "-gauge is too high", when speaking of the power cord.
Model NV-9600. American edition.
Problem that it will not eject and raise the cassette carriage. Although it tries to.
Power cable used is an "oblong/oval", three-pin type from Belden, reads "7 amps, 125v". Do these machines usually draw more power than 7 amps?
Further discovery:
Adjustable voltage switch is correct to multimeter-measured household voltage: 120V. Polarity of VCR's power jack is dubious though. No matter how hard I look through these bigass service manuals for several variants of these machines, I cannot find and a declaration of the VCR's female power jack. However, I do not know what would truly happen if the polarity of the plug and the VCR did not match. Maybe the VCR would still turn on? Partially function? I don't know.
"Don't worry about the voltage rating of the cable in this instance. Without wandering too far in to electrical theory, cable voltage ratings are quite nominal and generally refer to the insulative properties rather than conductive properties. I would be inclined to imagine that if this cable was sold in a 230VAC region it would be stamped 230VAC - it's just a differentiation between using it for domestic and HV use. Don't play fast 'n' loose with it, but in this instance, it's not a consideration.
Another way to think of this is imagine the cable is a hose, for Voltage we're considering the pressure we can put through the hose before it bursts. That's a function of the cross-sectional area of the hose wall and its construction materials. The width of the conductor is the flow-rate (current).
If you've ever replaced an HT lead on a car or lawnmower spark plug (US terminology might be different) you'll think it's a very thick cable, but the conductor inside is often a single strand of very thin copper with a very thick insulator as although it's very low current (flow rate) the potential (pressure) is very high.
Guessing that you're in the US, 7A @ 110VAC is 770W, that's quite a lot of power for a device like and I doubt that this machine requires anything near that, even considering it's age. This isn't going to be your problem. I would guess it draws something like 100-150W at full tilt, which is 1-1.5A, well within the specification of your cable.
This device should have an internal fuse of 1.2A (or thereabouts), this means it can't draw more than that without popping the fuse anyway, so the 7A cable is more than adequate.
Basically, it's not a cable related issue." - RobustReviews, from digitalfaq.com.
Update: 06-MAY-22, scrubbed male end of three-prong power cord to a shine. Female-end is in great shape already. No further success.
Update 09-MAY-2022: Standby switch does not light up, either. It probably hasn't since it's been in my possession. Important to note, though. Full, all four volumes of the service manual for this exact machine are on the way in the mail, and will be used to at least check the bottom of the unit for belts. I will likely need a car-jack to do so.
