PIONEER SPEC-2 POWER AMP FULLY SERVICED RECAPPED REBUILT AWESOME SOUND

This is an iconic amp based on a highly regarded non-export Pioneer power amp called the M77. One of the irritating secrets in early hi-fi was that the Japanese did not export what they considered their best products to the US and in most cases to anywhere else. The M77 was 180,000 YEN in Japan (approx $900 in US dollars) which was a fortune there in 1975. Bowing to pressure from US management, Pioneer started exporting the M77 to the US as the SPEC-2 in 1976.

This amp received 11 new caps, and many new transistors and diodes in the restoration. It is properly biased and looks good and sounds amazing. It is not unusual for a used SPEC-2 that just happens to work to sell for about the same price as this listing. This one has been gone over from top to bottom and is ready to rock! A tech who rebuilt one of these joked in a forum that you could use it to drive your arc welder when you were not listening to music.

According to Hi Fi Engine:

The Spec-2 is a 250W rack mount stereo power amplifier featuring a current limiter circuit, peak level meters, protection circuit, power switch on/off and impedance selector muting and a temperature detector.

This high power design employs a cascaded differential amplifier first stage, push-pull drive, and darlington triple push-pull circuit with all stages direct coupled (OCL).
