Pioneer SPEC-1 Stereo Solid State Pre Amplifier 1976 – 1980 – Silver

This Pioneer Spec-1 pre amplifier has been recently serviced and works well without issue. It part of a larger collection of vintage Pioneer equipment that we are now selling separately. All of which is extremely clean. Additional photos are available upon request. If interested please make us an offer!

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.

An electronic muting circuit, employing a reed relay, blocks surge noise associated with power switch operation.
