Hi Friends and fellow You Tubers This is part 3. the final of my colleagues Pioneer Stereo Receiver 280 Watt Music Power Amplifier which needs attention. Enjoy.... Richard PS Geoff is so pleased he has given me a couple of bottles of wine ! History/background information about one of the same period: From: Wikipedia: The Pioneer SX-1980 was a radio receiver that Pioneer Electronics Corporation introduced in 1978, to be matched with the HPM series of speakers. It is rated at a staggering 270 watts per channel into 8 ohms.However, in the September 1978 issue of Audio Magazine, Leonard Feldman did a spec test on the SX-1980 and concluded that the rating of 270 watts per channel was too conservative. He stated in his report: "Though the new [IHF mandated] "Dynamic Headroom" measurement is specified in dB, it should be mentioned that based upon the short-term signal used to measure the 2.3 dB headroom of this amplifier, it was producing nearly 460 watts of short-term power under these test conditions!" At an official rating of 270 watts per channel into 8 ohms with a 2.3 dB dynamic headroom, this makes the SX-1980 Pioneer's most powerful receiver, as well as being one of the most powerful receivers ever manufactured in the world, to date. Nothing had been built like it before. The SX-1980 is known for its total harmonic distortion (THD) rating of less than 0.03%, an astounding feat that has only been replicated by very few receivers at such a high power output; a feat that has ...
