The NVS-4000 Power Supply Unit found in some New Astro City cabinets (and perhaps others as well) are considered the Rolls Royce of PSU’s by some.
While it does lack a -5V output it is a behemoth boasting numerous inputs and outputs and the capacity to deliver enough power to drive a full NAOMI set up with JVS/JAMMA adapter and GD-ROM. It also has a built in stereo sound amplifier.
I’m not going dive deep into the hard data in this post. For now I’m just posting the pictures I took when I opened it up a couple of days ago for a clean up and a bit of troubleshooting regarding the wiring of the mono sound output.
The PSU with the cover and front/back panels removed.
Top view of the PSU with cooling plate removed.
The amplifier (a Sega Model 3 Stereo Amplifier is mounted upside-down below the PSU in the NVS-4000-01.
Lastly a picture of my now labelled loom from inside the PSU.
