Another of the silver faced Pioneer line the Pioneer SX-1050 was the little brother to the giant SX-1250 in 1976 and 1977. While it may not necessarily be considered a “Monster” receiver it is close. It weighs in at just over 50 pounds and has many of the features of the top of the line SX-1250. It’s rated at 120 per channel into 8 ohms as compared to the SX-1250 which was rated at 165 watts per channel. There were some fairly significant differences between the lower end Sx-850, SX-950 and the SX-1050. The SX-1050 incorporated a large toroidal transformer, a huge power supply with step-start circuit and two large capacitors, a step attenuator volume control, a shielded multi-gang tuning capacitor, and a well improved FM tuning section as well. So, the SX-1050 is really far more comparable to the SX-1250 then it is to the SX-850 and SX-950. It retailed at around $700.00.
The Pioneer SX-1050 was eventually replaced by the SX-1080 in 1978. The SX-1050 can be had for fairly reasonable prices. While the SX-1250 and SX-1980 are icons of the collecting world and therefore command sometimes ridiculously high prices, an average SX-1050 in good working condition can be had for $1000-$1800. A really nice one will bring over $2000. Not bad considering its build quality and performance.
