Pioneer Spec-1 Pre-Amplifier Vintage 1976/77 Audiophile Home Stereo 70s Made in Japan Hi-Fi Spec System
The Spec-1 has differential amplifier circuitry incorporated in the equalisation and tone control amplifiers. This is complemented by a dual positive and negative power supply system for all amplifier sections, which provides improved DC balance and stability, while eliminating click noises due to switching.

Very good cosmetic condition (see pics). Will be professionally packed and shipped for free with doubled boxes to guarantee damage free delivery.
