zenith: De-rattling Transoceanic 3000-1
This one is a 3000-1. Side by side with the Royal 7000, or a tube Transoceanic, it sounded very weak, with no bass to speak of, and an annoying buzz/rattle at even low volumes. The basic audio circuit and speaker is not a lot different than the 7000, so it must be something straightforward. It was close to unlistenable.
