Pioneer SA-7800 integrated stereo amplifier, manufactured in 1980, in excellent physical condition and fully tested and functional, weighing 12.8 kg with dimensions 42 cm (W) × 15 cm (H) × 37.6 cm (D).
Description from the seller
The Pioneer SA-7800 is an iconic stereo integrated amplifier produced in Japan between 1979 and 1981, a celebrated milestone of Pioneer’s legendary “Blue Line” series.
The unit for sale presents in excellent cosmetic condition and is fully functional in every part. Visually, it is preserved quite well, with the brushed aluminum front panel and the distinctive blue fluorescent indicators (Fluoroscan meters) that are splendid and bright.
Only minor signs of wear are noted on the front frame (details thoroughly documented and visible in the photos), which do not compromise in any way the overall aesthetic charm of the item. Electronically tested, it responds perfectly to every command without hiss or unwanted hum.
Unlike many vintage amplifiers with overly soft or rounded character, the Pioneer SA-7800 offers a surprisingly modern, transparent, and dynamic timbre. Thanks to the exclusive proprietary Non-Switching Amp circuit – which combines the efficiency of Class B with the distortion-free purity of Class A – it delivers an incredibly detailed, clean, and defined sound.
The bass is taut, deep, and well-proportioned; the midrange is textured and realistic (especially with vocals), while the extended highs shine without ever becoming fatiguing or harsh. It adapts with extraordinary versatility to any musical genre, from acoustic jazz to complex rock, maximizing the potential of both digital sources and the excellent integrated phono stage for turntables.
Technical Specifications
* Output power: 65 watts RMS per channel into 8 Ω (stereo)

Duties, if any, are the buyer’s responsibility.
