Rotel RX-403
Little is documented about the Rotel RX-403. No specification sheet, manual, or listing history has survived into the archive's collection, so a full technical profile isn't possible right now. The RX prefix points to a Rotel receiver of the same naming family the company used elsewhere in its line. The archive's record confirms no product type beyond "audio."
Here is what the record does show. A March 1978 test-report spread in HI-Fi-Stereo-Buyers (March 1978, p.57) appears to cover a Rotel receiver of this generation, and the archive's source index associates that spread with the RX-403. The surviving page copy describes a receiver with two magnetic phono inputs, aux, two tape loops, outputs for two speaker systems plus phones, and switches for power, a 20 dB audio mute, low and high filters, stereo/mono, and loudness compensation. The same fragment records 7.5 µV for full FM limiting. The model name is truncated in the OCR - the page cuts off mid-"Rot…" - so the attribution rests on the archive's index rather than a cleanly legible heading.
Confirmed facts, in full:
- Rotel RX-403 — catalogued under audio; no product type confirmed by the fact sheet.
- No confirmed specifications, release date, or original price documented.
- Period coverage appears to exist in HI-Fi-Stereo-Buyers, March 1978, pp.56–57.
That's the whole record. If you have an RX-403, a brochure, or a manual, the archive would welcome a copy.
