Realistic 31-2010
A catalog number with no paper trail.
Overview
The Realistic 31-2010 is a RadioShack catalog number that the surviving documentation doesn't explain. What the 31-2010 actually was - a receiver, a deck, a speaker, an accessory - the available record does not say.
The only indexed period chunk that mentions the 31-2010 at all comes from a 1985 equipment roundup in Audio (October 1985, p.240). The page is given over to equalizers, but the OCR is fragmentary enough that nothing on it can be pinned to this model with confidence. It's a breadcrumb, not a spec sheet. Whether the 31-2010 was itself an equalizer, or just shared a catalog spread with one, the archive can't answer from what's on hand.
The Realistic line is well documented in places. The STA receivers, the Minimus and Optimus speakers, and the SCT cassette decks all have their own entries here. The 31-2010 has no verified specifications, no confirmed production years, no original price, and no independent measurements. Anything said about its circuitry, its power rating, or its build would be invention. What can be said is that it carries a legitimate Realistic catalog number, and it appears in at least one 1985 audio publication's equipment pages.
For now the 31-2010 sits in the archive as a placeholder awaiting real documentation: a service manual, an owner's booklet, a catalog page, or a clear photograph of the unit itself. If one surfaces, this entry gets rewritten. Until then, treat any listing that claims specific specs for a "Realistic 31-2010" with skepticism. The number is real, but the details floating around it are not yet verified.
