Realistic SX-1250
The archive's record on this one is thin, and the little we have is tangled up in a dispute over what the unit actually is. What follows is what the sources establish, conflict included.
One source, a sales listing, presents the unit as a "Realistic SX-1250" stereo receiver. It gives some big specs: 125 watts per channel into 8 ohms, a signal-to-noise ratio of 100dB, and a weight of 41 pounds with dimensions of 20.5 by 6.5 by 16.5 inches. The same listing claims total harmonic distortion of 0.003% and a frequency response of 20-20,000 Hz ±0.3dB.
The other source contradicts the identity. A listing on adverts.ie, which appears to be a correction of a mislabeled sale, says the unit is not a Realistic SX-1250 at all. It is a Realistic STA-2000D. That source gives a different frequency response (5Hz to 100kHz, +0, -3dB) and notes that "the real SX-1250 was a Pioneer model, not Realistic."
Given the conflict, here is what can be said. No production years, original price, or tuner specifications are documented for any unit called the Realistic SX-1250. No listening impressions survive in the record. The correcting source suggests the listing refers to a Realistic STA-2000D that a seller badged as an "SX-1250", a model number borrowed from a far more famous Pioneer receiver. Until a source documents a genuine Realistic product with the SX-1250 name, this entry covers a mislabeled STA-2000D sale and not a distinct model in the Realistic catalog.
Known specifications attributed to the unit (source conflict noted):
- Power output: 125W per channel into 8Ω (RMS)
- Weight: 41 lbs
- Dimensions: 20.5" W × 6.5" H × 16.5" D
High-Fidelity (1977, p.24) noted the amplifier seemed just powerful enough to fill the room with sound. That sits far below the 125W claimed in the SX-1250 listing, so either the two sources describe different products or the sales listing's figures are unreliable.
